摘　　要：目的评价64层螺旋CT冠状动脉成像在诊断老年患者冠状动脉狭窄中的临床应用价值。方法回顾性分析39例患者行64层螺旋CT冠状动脉造影的老年患者(>65岁)的影像资料,在15段分段法的基础上,评价每段冠状动脉CT造影的图像质量;以传统X线冠状动脉造影为“金标准”,评价CT血管造影诊断冠状动脉狭窄及其程度的价值。结果多层螺旋CT冠状动脉造影(MSCTA)评价冠状动脉狭窄的敏感度、特异度、阳性预测值和阴性预测值分别为98.9%(90/91)、98.2%(426/434)、91.8%(90/98)和99.8%(426/427)。冠状动脉MSCTA与传统X线冠状动脉造影(CAG)对血管狭窄程度评价具有很好的一致性。结论多层螺旋CT冠状动脉成像在诊断老年人冠心病中具有重要的临床应用价值。Objective To evaluate the clinical value of 64 multi-detector row computed tomography coronary angiography（MSCTA） in detecting elderly patients＇ coronary stenoses. Methods The image data of thirtynine elderly patients who underwent 64-MSCTA of coronary arteries were retrospectively analyzed. The CT image quality of every coronary segment was estimated based on a 15-segmentation method. The conventional X-ray coronary angiography （CAG） was used as ＂gold standard＂, and the accuracy of 64-MSCTA in diagnosing coronary artery stenosis and confirming its degree was evaluated. Results The sensitivity, specificity, positive predictive value, and negative predictive value of 64-MSCTA in detecting coronary stenosis were 98. 9% （90/91） ,98.2% （426/434） , 91.8% （90/98） and 99.8% （426/427） respectively, and the correspondence of 64-MSCTA with X-ray CAG was very good in estimating the stenosis degree of coronary artery. Conclusion 64-MSCT coronary angiography has important clinical value in diagnosis of coronary artery disease of elderly patients.
