摘要：

【摘要】 <正>20世纪90年代以来,一系列不同于传统选择性造影的检查已经开始用于冠状动脉(冠脉)疾病的影像学诊断。越来越多的成人冠脉解剖异常被检出,其临床意义也受到国内、外学者的关注。但这些研究关注的多是冠脉的起源异常,没有关注副冠状动脉、冠状动脉发育异常等情况。本研究利用多层螺旋CT血管成像(MSCTA)观察成人冠状动脉解剖异常的特点,与选择性冠脉造影(SCA)进行对比,为临床早期诊断、治疗提供影像学依据。

Abstract: Abstract：Objective To use the noninvasive check means by Multi-slice Spiral CT Angiography to evaluate the value and clinical meaning in adult’s coronary artery anatomic abnomalies.Methods: MSCTA and clinical data of 760 patients were trospectively analysed.Results: Congenital Anatomic Variation of Coronary Artery 202 patients (26.58%, 202/760) were found by MSCTA among 760 patients. Take CAG test result as the "gold standard", the sensitivity of coronary artery anatomic abnomalies in MSCTA examination = 96.47%, specificity = 97.44%. Positive predictive value = 96.47%, negative predictive value = 97.44%.Conclusion: MSCT in the evaluation of anomalous coronary artery anatomy with high specificity, is a noninvasive and reliable evaluation of anomalous coronary anatomy in the first choice of imaging examination method.
