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.
评估64层螺旋计算机断层扫描(MSCT)冠状动脉造影在冠心病患者中的应用价值。
对58例患者进行冠状动脉64层螺旋CT检查。在一次屏气过程中完成静脉注射对比剂增强的64层螺旋计算机断层扫描冠状动脉造影,并回顾性重建心电图图像。所有轴位图像传输至外部工作站。重建图像经处理后得到容积再现(VR)、多平面重建(MPR)、曲面重组(CPR)及最大密度投影(MIP)。58例患者中有24例接受了选择性冠状动脉造影,比较两种检查结果。
冠状动脉的主要分支及分支情况显示清晰。38例患者的115支冠状动脉分支发现有冠状动脉斑块,斑块形态及狭窄程度可清晰区分。在有冠状动脉支架及搭桥血管的节段,其位置及远端血流显示良好。
64层MSCT冠状动脉造影是诊断冠心病的可靠方法,也是无创筛查和诊断冠状动脉疾病的有前景的技术。
