目的:评价64层螺旋CT对冠心病的诊断价值。方法:对25例典型病例的CT图片进行分析、总结,观察64层螺旋CT对冠状动脉的管腔狭窄程度及冠脉内斑块性质的显示能力,并对桥血管和支架通畅性进行观察。结果:近端冠脉中度以上狭窄的敏感度、准确度、阳性预测值分别为93.5%,90.3%,88.5%,对左主干及前降支病变诊断价值较高;对冠状动脉内软斑块显示较佳;对桥血管及支架通畅和有无再狭窄显示良好。结论:MSCT冠状动脉成像在冠心病筛查及冠状动脉支架术后和搭桥术后的随访发挥重要作用。
Objective: To evaluate the diagnostic value of 64-slice spiral CT in coronary heart disease. Methods: The CT images of 25 typical cases were analyzed and summarized. The degree of stenosis of coronary artery and the plaque quality of coronary artery were observed with 64-slice spiral CT. The patency of the vessel and stent were observed. Results: The sensitivity, accuracy and positive predictive value of proximal coronary artery stenosis were 93.5%, 90.3% and 88.5%, respectively, which had a higher diagnostic value for the left main and anterior descending coronary artery. Block showed better; on the bridge and stent patency and whether the restenosis showed good. Conclusion: MSCT coronary angiography plays an important role in coronary heart disease screening and follow-up after coronary stenting and bypass surgery.
