摘要(Abstract)：
目的探讨和评价16排螺旋CT在冠状动脉病变诊断中的价值。方法总结2003年8月至2004年9月于北京大学第一医院行16排螺旋CT冠状动脉成像检查的90例患者的资料,其中男性63例,年龄(67±9)岁。患者均于检查前后两周时间内进行了传统冠状动脉造影术。以冠状动脉造影结果为“金标准”,分析16排螺旋CT冠状动脉成像检查的灵敏度、特异度、阳性预测值及阴性预测值,并初步分析引起检查结果偏差的原因。结果16排螺旋CT冠状动脉成像检查共评价了冠状动脉直径>1.5mm的节段1267个,与冠状动脉造影“金标准”相比,16排螺旋CT冠状动脉成像检查诊断冠状动脉分支血管中度以上狭窄(>50%)的灵敏度为75.43%,特异度为95.88%,阳性预测值为74.58%,阴性预测值为96.01%,准确度为93.05%。结论16排螺旋CT冠状动脉成像检查可较为准确地诊断冠状动脉狭窄,可作为冠状动脉粥样硬化病变的筛查手段,是一种安全、有效、无创的检查方法。
