摘　　要：目的探讨双源cT冠脉血管成像对成人先天性冠状动脉起源异常的临床应用价值。方法回顾性分析经过西门子双源CT对720例患者行冠状动脉CTA检查的资料，利用该设备专用软件行衄，MPR，VR及CPR图像重组，必要时辅以4／）电影浏览所获冠脉CTA图像，首先评价其图像质量，再对15例冠状动脉起源异常病例的CTA图像进行分析和评价，并与临床症状进行对照。结果所有病例CTA图像质量均达诊断要求，其中评为4级者694例（96．39％），3级者21例（2．92％），2级者5例（0．69％）。15例冠脉起源异常者CTA图像质量均为4级，其中右冠脉起源异常9例（60％），左冠脉起源异常6例（40％）。其临床症状表现不一。结论双源CT冠状动脉血管成像简便、准确、图像质量高，可作为冠状动脉起源异常诊断的首选影像学检查方法。Objective To analyze the anomalous origin of coronary artery in 15 cases of patients who underwent DSCT coronary angiography retro-spectively and discuss its value of clinical application. Methods The data of about 720 patients who underwent the coronary angiography in Siemens Definition Dual Source CT （DSCT） between Oct 2010 and Aug 2011 were retrospectively analyzed. Using the special software of DSCT to reconstruct MIP.MPR.VRT and CPR image and, when necessary, with 4D movie, lastly we must estimate the image quality; Secondly, we need to analyze and e- valuate the characteristic of 15 cases＇ CT image which have been diagnosed with anomalous origin of coronary artery; thirdly, we must compare the re- sults with the clinical symptoms. Results All the image quality of the examination may achieve diagnosis requirements. From all of which, 694 cases as the grade 4（ 96.39 % ） ; 21 cases as the grade 3 （2.92 % ） and 5 cases as the grade 2（0.69 % ）. 15 cases of 720 have been diagnose with anomalous origin of coronary artery, 9 in the right and 6 in the left. Their image quality＇ s grade was all 4 . each of them have not the same performance. Conclu- sions DSCT coronary angiography have some benefit just like simple, accuracy, high image quality and so on, which may be used as the fast choice method for diagnosing anomalous origin of coronary artery.
