摘要
目的比较16层螺旋CT和冠状动脉造影对冠心病的诊断价值。方法23例患者行16层螺旋CT冠状动脉成像(回顾性心电门控、0.42s螺旋扫描),并与冠状动脉造影(CAG)对照。结果在23例患者中,MSCT显示轻度狭窄13处,中度狭窄12处,重度狭窄8处。CAG发现轻度狭窄8处,中度狭窄9处,重度狭窄7处。结论冠状动脉造影可能低估冠状动脉病变的严重程度,冠状动脉CT成像是对冠心病的早期诊断的有效补充。
Objective To evaluate the value of 16-slice spiral CT in diagnosis of coronary artery disease. Meth- ods 23 patients were studied by 16-slice spiral CT (retrospectively ECG-gating;0.42s rotation).The results were compared with coronary artery angiography. Results In 23 patients, MSCT showed 13 vessels with mild stenosis,12 vessels with significant stenosis and 8 vessels with high-grade stenosis. While CAG showed 8 vessels with mild stenosis,9 vessels with significant stenosis and 7 vessels with high-grade stenosis. Conclusions CAG may underestimates the degree of vascular lesions. MSCT can play a complementary role in the diagnosis of early CAD.
