A new benchmark study evaluated the effectiveness of three medical foundation models (FMs) for stratifying renal lesions in CT scans. While FMs showed promise by matching the performance of a 3D ResNet trained from scratch and requiring significantly less computational power, they did not surpass a traditional radiomics classifier. The study suggests that current generalist FM embeddings may not yet capture the detailed textural and shape variations crucial for distinguishing lesion subtypes, leaving radiomics as the current state-of-the-art for this specific task.
