MEDICAL IMAGING & AI DIAGNOSTICS
A Hybrid Model for Ultrasound Image-Based Breast Cancer Diagnosis Using EfficientNet-V2 and Vision Transformer
Background/Objectives: Breast cancer continues to be one of the most serious and common afflictions affecting women around the globe. Despite ultrasound imaging being an effective method for the detection of abnormalities in dense breast tissues, there are a number of drawbacks when utilizing this method, including the subjective nature of the imaging and the variant nature of the imaging due to the cognitive biases of the interpreting expert and the experience of the interpreting expert. The above factors are the cause of the increased need in the implementation of AI-driven models for diagnostic analysis. In this research, we provide a hybrid deep learning-based framework for cancer classifi-cation of the breast cancer ultrasound image dataset ('BUSI dataset').
Executive Impact
Methods: The con-tributing models of the proposed architecture involve the combination of a light ViT en-coder and an EfficientNetV2-RW-S feature extractor. The combination mentioned lever-age the positive sensitivities of the convolutional neural networks (CNNs) and the global reasoning neural networks (i.e., transformers) in the explanation of the architecture. The reason being, EfficientNetV2 diminishes the capture of the fine-grained morphological components of the lesions, edges, and echogenic variances of the tissue, whereas the trans-former model diminishes the long-range dependencies of the lesions and other surround-ing tissues. Results: The experimental results from the proposed hybrid model of the ar-chitecture demonstrates an enhanced classification accuracy of 97.95%, in contrast to the self-standing models of the architecture, the hybrid model supersedes the isolated ViT model (i.e., 89%) and the isolated CNN model (i.e., 80%) frameworks. Furthermore, the proposed model hybrid architecture also diminishes the overall self-attention computa-tional complexity of the proposed model by substantially diminishing the number of to-kens reaching an overall count of 10 (from the vast 197 tokens). This further leads to a substantial decrease in the memory and cost expended during the attention processes. Conclusion: Overall, this study proposes a method for the improved diagnostic and com-putational analysis, suggesting the proposed architecture to be a potential framework for use in the contemporary clinical environments.

Clinical Integration Potential
The model's efficient computational footprint and high accuracy make it suitable for integration into existing clinical workflows, offering rapid, interpretable insights for radiologists and oncologists. Its ability to balance sensitivity to malignant lesions with noise resilience positions it as a robust tool for improving diagnostic consistency and reducing practitioner cognitive load. This translates directly into faster patient triage and potentially earlier intervention.
