摘要
目的:本研究目的在于前瞻性评估在广泛临床患者中,具有高时间分辨率(83ms)的高速双源计算机体层扫描(DSCT)用于识别显著冠状动脉病变(管腔直径减少≥50%)的诊断价值。背景:使用先前的时间分辨率有限的CT时,心脏的运动伪影可降低冠状动脉成像的质量。
Objectives: Our objective was to prospectively evaluate the diagnostic performance of the high-speed dual-source computed tomography scanner(DSCT), with an increased temporal resolution(83 ms), for the detection of significant coronary lesions(≥ 50% lumen diameter reduction) in a clinically wide range of patients. Background: Cardiac motion artifacts may decrease coronary image quality with use of earlier computed tomography scanners that have a limited temporal resolution. Methods: We prospectively studied...
