New metric improves coronary artery segmentation analysis for FFR-CT

Researchers have developed a new metric called the Bifurcation Connectedness Score (BCS) to evaluate the quality of coronary artery segmentation in medical imaging. Standard metrics like Dice can achieve high scores even when segmentations sever critical arterial branches, leading to incorrect treatment decisions. BCS specifically assesses the connectedness at bifurcation points, a property crucial for accurate Fractional Flow Reserve derived from CT angiography (FFR-CT) simulations. Higher BCS scores correlate with improved agreement between FFR-CT decisions derived from predicted versus ground-truth geometries, particularly in cases of severe disease. AI
