背景:多探头CT(MDCT)已被推荐作为评估冠状动脉解剖结构的无创性方法。目的:在多中心研究中确定采用16层CT基于独特的定量分析方法检测阻塞性冠状动脉疾病的诊断准确度。设计、机构和患者:自11个参与地点前瞻性纳入2004年6月至2005年3月间临床转诊拟行非急诊冠状动脉造影的238例患者。
Background: Multi-probe CT (MDCT) has been proposed as a noninvasive method of assessing the anatomy of coronary arteries. OBJECTIVES: In a multicenter study, a 16-slice CT was used to determine the diagnostic accuracy of obstructive coronary artery disease based on a unique quantitative assay. DESIGN, INSTITUTIONS AND PATIENTS: 238 prospectively enrolled 238 patients enrolled in non-emergency coronary angiography between June 2004 and March 2005 from 11 participating sites.
