1. INTRODUCTION

Recent advancements in artificial intelligence (AI) have transformed the landscape of medical imaging by enhancing diagnostic accuracy, reducing interpretation time, and enabling early disease detection. Among these developments, transformer-based architectures have emerged as powerful tools for analyzing complex visual data due to their ability to model long-range dependencies and capture global contextual information in medical scans [1][2]. This study investigates the application of a transformer-based deep learning model to automate and improve tumor detection in MRI and CT images, focusing particularly on brain and lung cancers—two of the most prevalent and lethal tumor types worldwide [3][4].

Despite the significant progress made by convolutional neural networks (CNNs) in medical imaging, their limited receptive fields and difficulty in capturing global spatial relationships often result in suboptimal performance in detecting small or complex tumors [5][6]. Additionally, current AI systems frequently lack interpretability and generalization, especially when dealing with multi-modal data such as MRI and CT scans, which are crucial for comprehensive tumor analysis [6][7]. There is a pressing need for an accurate, explainable, and scalable diagnostic model that can integrate and process diverse imaging modalities while maintaining high sensitivity and specificity.

Transformer architectures are particularly suitable for medical imaging because they capture long-range spatial relationships that are essential for identifying tumors with irregular shapes or diffuse boundaries. Unlike CNNs that operate through localized filters, transformers use global self-attention, enabling the model to contextualize tumor regions within the entire anatomical structure. This advantage becomes even more critical in multi-modal settings, where MRI and CT scans provide complementary information on soft tissues and density variations. While alternative architectures such as graph neural networks and diffusion models have emerged, they often require complex preprocessing pipelines or extensive training data—constraints that hybrid transformers can overcome more efficiently.

The primary objective of this research is to develop and evaluate a transformer-based deep learning framework for tumor detection across MRI and CT imaging modalities. Specific goals include:

1. Designing a hybrid vision transformer (ViT) model tailored for high-resolution medical imaging.
2. Fine-tuning the model using annotated datasets of brain and lung tumors from multi-modal sources.
3. Evaluating the model’s diagnostic performance in terms of accuracy, sensitivity, specificity, and interpretability.
4. Comparing the proposed method against state-of-the-art CNN-based systems and existing AI tools in oncology imaging [8][9].

The key contributions of this study are as follows:

• Introduction of a unified transformer-based architecture capable of learning from both MRI and CT data.
• Demonstration of superior performance in tumor localization and classification compared to traditional models.
• Use of attention maps to enhance clinical interpretability, addressing the "black-box" issue in AI [10][11]
• Validation using diverse datasets, supporting generalizability and real-world applicability in clinical radiology [12][13].

Transformers have been widely explored in specific domains, yet most prior studies treat MRI and CT independently or rely on late-fusion strategies. The novelty of this work lies not in cross-modality usage alone but in the unified, end-to-end hybrid Vision Transformer architecture that processes MRI (BraTS) and CT (LUNA16) data within a single framework [14]-[16]. By integrating convolutional layers for local spatial encoding with transformer blocks for global context modeling, the proposed hybrid design addresses longstanding limitations in CNN-based tumor detection [6][7], including restricted receptive fields, modality-specific overfitting, and weak interpretability [17][18].

In doing so, this research pushes the frontier of AI in medical diagnostics by delivering a robust, explainable, and multi-modal solution that addresses critical gaps in current imaging technologies. The findings hold promise for integration into radiological workflows, enhancing diagnostic confidence and supporting early intervention strategies in oncology. The research contribution is threefold: (1) development of a hybrid Vision Transformer capable of unified MRI–CT processing, (2) performance improvements over state-of-the-art CNN-based tumor detection models on BraTS and LUNA16 datasets, and (3) enhanced clinical interpretability through transformer attention maps that visualize tumor-relevant regions.

2. LITERATURE REVIEW

Artificial intelligence (AI) has emerged as a transformative force in medical imaging, enabling faster, more accurate, and highly reproducible diagnostic workflows. The shift from traditional rule-based approaches to data-driven deep learning models has unlocked new potential in disease detection, prognosis, and treatment planning. [5] outlined the foundational role of deep learning techniques in biological image analysis, emphasizing their adaptability across diverse imaging modalities.

[10] emphasized that reproducibility, explainability, and multimodality are the pillars upon which AI-driven diagnostics should evolve. [9] provided a macro-level analysis of AI-driven innovation in imaging, from image acquisition to advanced clinical decision support. Meanwhile, [17] introduced the concept of integrating language models such as ChatGPT into medical imaging, promoting human-AI interaction and interpretability.

Tumor detection has been one of the most impactful areas of AI application. [3] reviewed progress in neuro-oncology, highlighting AI’s utility in brain tumor classification, prognosis, and treatment response prediction. Similarly, [19] surveyed techniques for brain tumor detection, indicating that transformer models offer promising results compared to legacy CNNs.

[20] explored AI and machine learning’s role in early-stage tumor detection, while [8] presented a comparative analysis of deep learning models for lung cancer diagnosis, supporting the notion that transformer models offer better long-range context capture.

[14] demonstrated the use of Vision Transformers (ViTs) for ovarian cancer classification, affirming their superior performance in dealing with complex spatial structures. [1] offered a broader review on ViTs in thyroid carcinoma diagnosis, positioning them as a disruptive alternative to CNN-based approaches.

The fusion of multi-modal data has shown to enhance diagnostic outcomes significantly. [7] conducted a comprehensive review of techniques, algorithms, and clinical applications of multi-modal image fusion. [6] similarly emphasized the value of deep learning in multi-modal fusion for complex disease detection, also [6] proposed a neuroimaging informatics framework for PET-CT data, revealing insights into rare tumor patterns.

[18] presented a future outlook on multimodal AI systems that integrate imaging with clinical metadata, highlighting the challenges in generalization and interoperability. [12] demonstrated the utility of AI-based segmentation in prostate cancer, especially in combining PET and MRI for tumor volume assessment.

[25] critically reviewed deepfakes in medical imaging, cautioning against ethical misuse and calling for robust detection frameworks to preserve integrity in AI systems.

Vision Transformers (ViTs) have reshaped the capabilities of medical imaging AI by offering better global feature extraction. [2] applied ViTs to ultrasound images, achieving higher precision in anatomical structure detection compared to traditional models. The success of ViTs in cancer classification and anatomical segmentation opens new pathways for developing robust, scalable diagnostic tools.

Despite the advancements documented in existing literature, several gaps remain unaddressed. Most transformer-based studies still rely on large training datasets and lack robust generalization across modalities, limiting their clinical applicability. Furthermore, prior works rarely explore unified architectures capable of handling MRI and CT simultaneously; instead, they depend on separate pipelines or late fusion approaches, which introduce feature-alignment problems. Computational complexity and interpretability also remain major limitations of current transformer models. These gaps highlight the need for a unified, explainable, and computationally efficient hybrid transformer architecture—motivating the approach proposed in this study.

3. METHOD

This section presents the methodology behind the proposed hybrid Vision Transformer (ViT) framework for tumor detection in MRI and CT scans. The method is designed to support multi-modal learning, improved global context modeling, and clinically meaningful interpretability. It includes preprocessing, hybrid patch embedding, transformer encoding, cross-modal fusion, classification, attention-based explainability, and training procedures. A complete flowchart of the research pipeline is shown in Figure X, which should be placed at the beginning of Section 3 to enhance clarity.

1. Overall Architecture

The proposed framework adopts a hybrid Vision Transformer architecture, where “hybrid” refers to the integration of convolutional layers with transformer blocks. Instead of using a pure linear projection for patch embedding, a shallow CNN stem is applied to extract low-level spatial and texture features that are critical in medical imaging. These convolutional layers enhance the model’s ability to detect fine-grained tumor boundaries before tokens are passed to the transformer encoder.

The proposed framework adopts a Vision Transformer (ViT) architecture with a hybrid design, optimized for high-resolution medical images. The system processes both MRI and CT scans using a unified pipeline to enable multi-modal learning. The architecture consists of the following modules:

1. Preprocessing and Patch Embedding
2. Transformer Encoder
3. Multi-Modal Feature Fusion
4. Tumor Classification Head
5. Attention-Based Explainability Module

The overall architecture of the proposed system is illustrated in Figure 1. It outlines the sequential stages from image preprocessing through patch embedding, transformer encoding, multi-modal feature fusion, to the final classification output. The system is designed to accommodate both MRI and CT inputs and generate tumor predictions with visual explanations.

Figure 1. Architecture of the Proposed Transformer-Based Tumor Detection System

2. Dataset Description and Fine-Tuning Scope (INSERT BEFORE PREPROCESSING)

The model is fine-tuned on two widely used benchmark datasets:

• BraTS 2021 (Brain Tumor MRI Dataset): 3 tumor types (glioma, meningioma, pituitary), 3,500+ MRI slices after preprocessing.
• LUNA16 (Lung CT Tumor Dataset): 888 CT scans with annotated lung nodules.

These datasets were chosen due to their high annotation quality, multi-modal nature, and widespread acceptance in tumor analysis research.

3. Preprocessing and Patch Embedding

MRI and CT scans come from different modalities, with distinct intensity distributions and noise characteristics. Therefore, each modality follows its own preprocessing pipeline consisting of:

• modality-specific intensity normalization
• resizing to 256 × 256
• CLAHE (MRI) or windowing (CT)
• patch extraction of size 16 × 16

Separate patch-embedding pipelines are used for MRI and CT inputs:

• Each image is first processed by a modality-specific CNN stem.
• The resulting feature map is split into patches and linearly projected into the transformer dimension D.
• A learnable positional embedding is added to maintain spatial ordering.

This ensures that MRI and CT distributions are not mixed prematurely, improving multimodal robustness. Each patch is flattened into a 1D vector and projected to a latent dimension D via a trainable linear layer:

Where,  is the embedding weight,  is the bias term.

A learnable position embedding  is added to retain spatial information:

Figure 2 shows the data preprocessing pipeline. This includes image normalization, patch segmentation, linear projection, and the addition of positional embeddings before passing them into the transformer encoder.

Figure 2. Data preprocessing pipeline used before feeding images into the transformer model

4. Transformer Encoder

The transformer encoder consists of L layers, each composed of:

1. Multi-Head Self-Attention (MHSA)
2. Feed-Forward Network (FFN)
3. Layer normalization
4. Residual connections

Equations (3) and (4) follow the standard ViT formulation but serve a key purpose:

• MHSA models global spatial dependencies across the entire image.
• FFN performs non-linear transformation of these global features.
• Residual paths improve gradient flow and stabilize convergence.

To help readers unfamiliar with transformers, the [CLS] (class token) is a special learnable token added to the sequence. It aggregates global image information through the encoder layers and is used by the classification head as the final task representation.

The embedded sequence is passed through L transformer layers, each consisting of Multi-Head Self-Attention (MHSA) and Feed-Forward Networks (FFN), with layer normalization and residual connections:

Each attention head computes attention weights as:

Where,  and . The outputs from all heads are concatenated and linearly transformed.

5. Multi-Modal Feature Fusion

The original weighted-sum fusion  was replaced with a cross-attention fusion module, addressing the reviewer’s concern regarding simplicity. Let  and  be modality-specific transformer outputs. Cross-attention is computed as:

The final fused feature is:

where  is a learnable scalar.

This cross-attention mechanism allows each modality to query clinically relevant information from the other, enabling richer multi-modal feature interaction than simple summation. It also improves alignment between MRI soft-tissue features and CT density-based features. Figure 3 depicts how features from the MRI and CT modalities are independently extracted, weighted, and combined using a learnable scalar α. This fusion enhances the model’s ability to interpret spatially distinct but clinically relevant information.

Figure 3. Multi-modal fusion of MRI and CT features using a learnable attention weight

6. Tumor Classification Head

The fused feature sequence is passed to the class token [CLS], and a feed-forward classifier computes the tumor probability:

The class token acts as a global summary vector integrating multi-modal representations through all transformer layers.

7. Loss Function

The total loss is defined as:

1. Attention Regularization Loss ()

The attention regularization term encourages the model to allocate higher attention weights to tumor regions. Let  denote the attention map and M the ground-truth tumor mask:

This penalizes attention placed outside tumor structures.

2. Role of  and

• A higher  forces the model to focus strongly on tumor regions.
• A lower  allows the model to attend broadly across the image.
•  balances between classification accuracy and explainability.

In our experiments:

•  = 1
•  = 0.3 produced the best trade-off.

8. Explainability via Attention Maps

Attention weights from the final transformer layers are visualized to highlight tumor regions. These maps are upsampled and overlaid on the original scans to provide clinical interpretability, aligning with recent efforts to enhance explainability in AI-based diagnostics [10],[17].

9. Training Strategy and Hyperparameter Rationale

• Learning rate 3e-5: optimal for fine-tuning transformer models without catastrophic forgetting.
• Batch size 16: selected to balance GPU memory constraints and batch-level diversity.
• Cosine annealing scheduler: stabilizes convergence.
• Data imbalance handling: minority-class oversampling + weighted loss.
• Overfitting mitigation: dropout (0.1), augmentation, early stopping.
• Validation strategy: 5-fold cross-validation to ensure robustness.

These choices were validated experimentally and align with transformer fine-tuning best practices.

4. RESULTS AND DISCUSSION

This section presents the experimental results.

10. Benchmark Datasets and Experimental Setup

Experiments were conducted using two widely recognized medical imaging benchmarks to ensure reproducibility:

• BraTS 2021 (Brain MRI Tumor Dataset):
  Includes multi-contrast MRI sequences and labels for glioma, meningioma, and pituitary tumors. After preprocessing, 3,512 MRI slices were used.
• LUNA16 (Lung CT Tumor Dataset):
  Contains 888 CT scans with radiologist-annotated pulmonary nodules derived from the NLST screening trial.

Both datasets are selected due to their established use in tumor detection benchmarks and their suitability for evaluating cross-modality performance. A 70-15-15 split was used for training, validation, and testing, and all experiments were repeated across five cross-validation folds to ensure statistical robustness.

11. Baseline Models and Justification

To demonstrate the effectiveness of the proposed hybrid ViT, we compared performance against strong and widely used baselines:

• ResNet-50 and DenseNet-121:
  High-performing CNNs commonly used in radiology imaging research.
• Hybrid CNN+LSTM / 2D+3D CNN:
  Architectures that incorporate temporal/spatial context and remain competitive for tumor detection tasks.

These baselines were selected because they represent state-of-the-art CNN approaches in comparable MRI and CT imaging studies and are commonly reported in literature assessing tumor classification models.

12. Single-Modality Performance

The proposed Vision Transformer (ViT) model outperformed existing CNN-based methods and hybrid architectures. The results for both MRI and CT datasets are shown in Table 1 and Table 2.

Table 1. Performance on BraTS Brain MRI Dataset (5-fold mean ± SD)

Table 2. Performance on LUNA16 Lung CT Dataset (5-fold mean ± SD)

13. Multi-Modal Fusion Performance

Reviewers requested evidence that fusion improves performance. Here is the new, separate multi-modal experiment as shown in Table 3:

Table 3. MRI–CT Multi-Modal Fusion vs. Single Modality

Key Findings:

• Fusion improves overall detection performance by +1.4% accuracy vs. MRI-only.
• Statistically significant improvement (p < 0.01 using paired t-test).
• Demonstrates that MRI contributes soft-tissue detail while CT adds structural density cues.

14. Statistical Significance Testing

To confirm that improvements are not due to randomness:

• We performed paired t-tests comparing our hybrid ViT to each baseline across 5 folds.
• All comparisons showed p < 0.01, confirming statistical significance.
• Confidence intervals (95%) for accuracy improvements were narrow (±0.3–0.5%), showing stable performance.

 One key advantage of using transformers is their attention mechanism, which improves interpretability. Figure 4 shows heatmaps highlighting tumor regions. The attention maps were validated by expert radiologists and aligned with radiological features in 91% of cases. To further demonstrate the model's interpretability, we visualize attention maps generated by the final layers of the transformer architecture. These maps highlight regions in the input scans that the model deems most relevant for tumor classification. By overlaying the attention weights on the original MRI and CT images, we provide a visual explanation of the decision-making process. This enhances clinical transparency and aligns model predictions with radiological findings. Figure 5 illustrates representative examples of such attention overlays across both imaging modalities.

Figure 4. Attention map overlay generated by the transformer model showing tumor localization. Red- highlighted zones correspond to areas with high attention weights indicating potential tumor presence

Figure 5. Attention Map Overlay Highlighting Tumor Localization

15. Ablation Study with Corrected Interpretation

An ablation study was conducted to assess the impact of each component in the model. As shown in Table 4, removing the attention map or using only a single modality (MRI or CT) significantly degraded performance.

Table 4. Ablation Study (MRI Task)

• Pretraining contributes a +6% accuracy boost—showing strong transfer learning benefits.
• Attention regularization improves tumor localization.
• Fusion provides the largest performance jump, confirming multi-modal synergy.

16. Comparison with Existing Studies

Our findings align with previous work showing the superiority of transformer architectures in medical imaging. For example, Ani et al. [14] reported a 3–4% improvement over CNNs for ovarian cancer classification, while Habchi et al. [1] achieved similar margins in thyroid carcinoma detection. Compared to these studies, our hybrid ViT achieves a higher relative gain (+5.4% vs. CNN baselines), largely due to the cross-attention fusion mechanism and attention regularization.

17. Scientific Discussion

• (i) Main Findings

The proposed hybrid ViT significantly outperforms CNN-based and hybrid CNN-LSTM models on both MRI and CT tasks, and achieves further gains through cross-modal fusion.

• (ii) Comparison with Other Studies

Our results exceed the performance reported in recent ViT medical imaging studies [1],[14], confirming the value of hybrid architectures and attention mechanisms.

• (iii) Implications and Explanation

The improved performance arises from:

• CNN stem enabling better local texture extraction
• Self-attention capturing long-range tumor context
• Cross-modal fusion aligning MRI and CT cues
• Attention regularization improving interpretability
• (iv) Strengths and Limitations

Strengths:

• Multi-modal learning
• High explainability
• Strong statistical validity

Limitations:

• Small lesions are harder to detect
• Requires more computational resources than standard CNNs
• No PET or ultrasound modalities included yet

5. CONCLUSIONS

This study presented a unified hybrid Vision Transformer (ViT) model for automated tumor detection in MRI and CT scans, evaluated on two benchmark datasets—BraTS (MRI) and LUNA16 (CT). The proposed model achieved 95.4% accuracy on BraTS and 93.6% on LUNA16, and the multi-modal cross-attention fusion framework further improved performance to 96.8% accuracy, representing a 1.4% gain over MRI-only models and a +3–6% improvement in sensitivity over leading CNN baselines. These quantitative gains confirm that transformer-based architectures, when combined with convolutional feature stems and attention-guided fusion, offer substantial advantages for medical image analysis.

The core theoretical contribution of this research is the development of a unified hybrid ViT architecture with modality-specific CNN stems and a cross-attention fusion module, enabling MRI and CT information to be integrated within a single, explainable end-to-end framework. Additionally, the formulation of an attention regularization loss strengthens alignment between model attention and tumor regions, enhancing transparency and clinical interpretability. Together, these components advance the emerging field of explainable transformer models in radiology.

While the findings demonstrate strong potential, several limitations must be acknowledged. First, the model relies solely on imaging data, without incorporating clinical metadata such as age, symptoms, or genomic markers, which may improve diagnostic granularity. Second, small or low-contrast lesions remain challenging, particularly in CT scans where attention occasionally misallocates to vasculature. Third, although cross-validation confirms robustness, prospective clinical validation and real-time integration studies were not performed, limiting immediate claims of deployability. Finally, computational demands remain higher than classical CNNs, which may affect scalability in low-resource clinical settings.

These limitations directly motivate future research directions. To address reliance on imaging alone, future work will incorporate multi-modal patient metadata and explore joint vision–language transformer models. Expanding the framework to additional modalities (e.g., PET, ultrasound) will help assess generalizability across imaging domains. Further, evaluating interpretability using quantitative metrics and formal radiologist-rating protocols will strengthen clinical credibility. Prospective studies on runtime optimization and deployment feasibility—such as edge-accelerated ViT variants—are also needed before clinical adoption can be realistically considered.

Overall, this study contributes new knowledge to medical AI by demonstrating how hybrid transformers with cross-modal fusion and attention regularization can deliver statistically robust improvements in tumor detection while offering greater transparency than conventional deep learning systems. By providing a unified, explainable architecture for MRI–CT tumor analysis, this work lays a foundation for future multi-modal diagnostic tools and encourages continued exploration of transformer-based approaches in clinical radiology.
