CTA evaluates coronary stent patency

CTA evaluates coronary stent patency By James Brice Cohort studies presented in a scientific session Sunday showed progress toward employing coronary CT angiography to evaluate the patency of coronary artery stents. Building on research presented in the two preceding years, the results covered during this year's sessions indicate that the protocols have improved for examining stent patency with 64-slice or dual-source CT. Promising findings from this still-preliminary work justify their adoption as alternatives to x-ray angiography by academic sites and will lead to more research on larger patient populations to move them into general use.
