Researchers have developed X-LMC, a novel spatiotemporal framework designed to automate the scoring of leptomeningeal collateral (LMC) from digital subtraction angiography (DSA) scans. This automated system aims to overcome the variability and manual effort associated with current clinical grading methods like the ASITN/SIR scale. X-LMC utilizes a DINOv2 backbone for spatial encoding, cross-view attention for fusing orthogonal projections, and a recurrent network for modeling contrast bolus dynamics. Evaluations on a dataset of 134 patients demonstrated that X-LMC achieved higher accuracy and consistency compared to existing static and spatiotemporal baselines, aligning with human inter-rater agreement.
