Breast cancer screening reduces breast cancer mortality through early detection, with mammography as the most widely used imaging modality. However, radiologist interpretation is time-consuming, and existing AI tools still suffer from missed subtle lesions an...

Preoperative phenotyping of vessels that encapsulate tumor clusters (VETC) and microvascular invasion (MVI) is clinically important in hepatocellular carcinoma (HCC) diagnosis and treatment. While most studies rely on MRI, CT-based prediction remains limited...

Low-field MRI suffers from intrinsically low SNR, which limits image quality and slows wide clinical adoption. Deep learning–based denoising shows strong promise, yet supervised training requires paired high-quality references that are rarely available for lo...
