Abstract
To determine the ability of contrast-enhanced retrospectively electrocardio graphic-gated multislice spiral computed tomography (MSCT) for the noninvas ive visualization of coronary artery bypass grafts and detection of signifi cant bypass stenoses, we performed a direct comparison to invasive coronary angiography in a group of 65 patients with a total of 182 coronary artery bypass grafts. MSCT demonstrated a high sensitivity (97%) and specificity ( 98%) for the evaluation of bypass graft patency and a satisfactory diagnost ic accuracy for the detection of high-grade bypass stenoses (sensitivity 75 %, specficity 92%) in evaluable bypass grafts.
