Multi-Granularity 3D Kidney Lesion Characterization from CT Volumes

arXiv:2606.04365v1 Announce Type: cross Abstract: Radiology reports describe kidney lesions by type, size, enhancement, and attenuation, yet existing 3D methods predict only at the patient or organ level. We reformulate kidney CT characterization as a per-lesion set-prediction task: one model emits a variable number of lesions per kidney, each with four clinical attributes. We curated 2,619 CT volumes from 788 patients at one academic medical center, with multi-granularity side- and per-lesion labels, and used KiTS23 (489 cases) for zero-shot external validation. We propose \textbf{LesionDETR}

Why this matters
Why now

The continuous advancements in AI, particularly in computer vision and deep learning, are enabling more sophisticated medical image analysis tools now.

Why it’s important

This development can significantly improve the accuracy and efficiency of kidney lesion characterization in radiology, leading to earlier and more precise diagnoses for patients.

What changes

Radiologists will have more granular and automated tools for analyzing kidney CT scans, potentially reducing diagnostic errors and improving treatment planning for kidney diseases.
