4排螺旋CT对冠状动脉粥样硬化性心脏病的临床价值

Clinical value of 4 - detector row spiral CT with coronary artery disease patients

目的 探讨4排螺旋CT冠状造影在诊断冠状动脉粥样硬化性心脏病(简称冠心病)中的价值.方法 收集临床上初步拟诊为冠心病的35例患者的93支血管并进行螺旋CT冠状造影和常规冠状动脉造影检查,对比分析螺旋CT冠状造影的准确性.结果 螺旋CT冠状造影发现47支冠状动脉狭窄,常规冠状动脉造影检查发现51支冠状动脉狭窄.螺旋CT冠状造影发现的44支血管狭窄与冠状动脉造影结果一致,敏感性为86.3%,特异性为100%.螺旋CT冠状造影和常规冠状动脉造影检查结果大体一致.结论 4排螺旋CT冠状造影可作为诊断冠心病的一种无创筛选检查方法,提高了冠状动脉造影诊断冠心病的符合率.

Objective To explore the diagnosticclinical value of 4 -detector row spiral CT with coronary artery disease. Methods Spiral CT coronary angiography (CTCA) and conventionalcoronary angiography(CAG) were used in 93 arteries of 35 coronary artery disease patients. To analysis the precise level of CTCA through contrasting. Results CTCA showed the angiostegnosis with 47coronary arteries,CAG showed theangiostegnosis with 51coronary arteries. The angiostegnosis results of 44 coronary arteries were same with CTCA and CAG. The total sensitivity of CTCA was 86.3% , and specificity was 100%.The results of CTCA and CCA were coincidentalin general. Conclusions 4 - detector row spiral CT can be used as a noninvasive screening method for the patients with suspected coronary artery disease, and the coincidence ratewasincreased ofcoronary angiography with coronary artery disease.
