Multi-Granularity 3D Kidney Lesion Characterization from CT Volumes
Researchers developed LesionDETR, a deep learning model that characterizes kidney lesions in CT scans at the individual lesion level rather than patient or organ level, predicting lesion type, size, enhancement, and attenuation. The model achieved strong performance on bilateral abnormality detection (AUC 0.799-0.817) but revealed that rare solid lesions remain challenging, suggesting data collection rather than architectural improvements are needed next.
