CAD-RADS 5/G in a 86-year-old man with a history of three-vessel coronary bypass graft surgery who underwent coronary CT angiography to evaluate the patency of the grafts. Curved multiplanar reformatted CT angiographic image shows a RSVG from the ascending aorta to distal RCA. There is dense wall calcification with total luminal occlusion of the graft. All other bypass grafts were patent (not shown). The patient was assigned CAD-RADS 5/G category. Invasive coronary angiography was recommended.CAD-RADS: Coronary Artery Disease Reporting and Data System, CT: computed tomography, RCA: right coronary artery, RSVG: reversed saphenous vein graft.
