To synthesize the evidence on the association between the preoperative functional liver imaging score (FLIS) and post-hepatectomy liver failure (PHLF), overall survival (OS), and the discriminative performance of FLIS for PHLF prediction, in patients undergoing hepatectomy for hepatocellular carcinoma (HCC). PubMed, Em...

Chance-calibrated neighborhood discordance (CANDOR) is applied to 22 frozen encoders on 605,443 images from 20 public datasets, covering 8 binary tasks in 7 domains, and finds that on every task, the best encoder is below 1/2.
Differential privacy (DP)'s effect in medical imaging is typically evaluated only through end-to-end performance, leaving the mechanism of privacy-induced utility loss unclear. We introduce Differential Privacy Representation Geometry for Medical Imaging (DP-RGMI), a framework that interprets DP as a structured transfo...

Medical image encoders from different groups are increasingly treated as interchangeable, on the assumption that scale and clinical supervision concentrate their representations onto a shared structure. Whether this convergence is real, what produces it, and whether it is clinically usable are untested, and the similar...

It is shown that Monte Carlo dropout, applied to a multi-task chest-radiograph classifier, provides an epistemic uncertainty signal that tracks generalisation across training-set scales and flags confident yet error-prone predictions.

It is demonstrated that pairing a genomic language model with widely available clinical imaging can serve as a hypothesis-free discovery tool for gene--imaging associations invisible to conventional approaches.
