Abstract
To assess the value of 64-slice spiral computed tomography (MSCT) coronary angiography in patients with coronary heart disease. Fifty-eight patients were performed 64-slice spiral CT in coronary artery. Intravenously contrast enhanced 64-slice spiral computed tomography coronary angiography was achieved during a single breath hold, and ECG images were reconstructed retrospectively. All axial images were transferred to an external workstation. The reconstructed images were processed into volume rendering (VR) and multiplanar reconstruction (MPR) and curved planner reconstruction (CPR) and maximum intensity projection (MIP), 24 of the 58 patients underwent selective coronary artery angiography, the outcomes of the two kinds of examination were compared. The main branches and of the sub-branches of the coronary artery were clearly displayed. 115 coronary artery branches of 38 patients were found coronary plaques, plaque morphology and stenosis extent could be clearly differentiated. In the segments with coronary stents and bypass graft, the position and distal blood flow were well showed. 64-slice MSCT coronary angiography is a reliable diagnostic method for coronary heart disease and promising technique for noninvasive screening and diagnosis of coronary artery disease.
