Computed tomography (CT) has enabled noninvasive evaluation of coronary bypass graft patency. Thirty-three patients operated on with 75 venous coronary bypass grafts were studied in the early postoperative period. Scans were taken with geometric magnification with a field of view of 16 or 24 cm, which gave a high spatial resolution. In 12 patients, complementary angiography was performed, which demonstrated occlusion of six of the grafts. Blind review of the CT examinations demonstrated 67 out of 70 patent grafts (96%).
