| Objective To discuss the method of multi-slice spiral CT coronary angiography and the factors that influence the image quality. Methods 100 patients underwent MSCT coronary angiography, contrast media was injected intravenously(1 ml/kg) at the speed of 5 ml/s. The reconstructed images were then processed into volume rendering (VR) and multi-planner reconstruction (MPR) and curved planner reconstruction (CPR) and maximum intensity projection (MIP). Results Among the 100 patients, the heart-rate, the coronary artery and the clearly demonstrated coronary artery, relatively and respectively, were below 60/min 100, 95 (95%) and 60-70/min 160, 150 (93%) and 70-80/min, 100, 80 (80%) and >80/min, 40, 20 (50%). Conclusion Multi-slice spiral CT coronary has very high clinical value for diagnosis of the coronary artery disease and the recheck evaluation of blood vessel bridge building operation and inner bracket placement. |
