摘要
目的初步探讨双源CT冠状动脉成像时利用仿真内镜诊断冠状动脉疾病的潜在价值。方法使用Fly-through软件对40例双源CT冠状动脉成像病例行仿真内镜观察,并与CT冠状动脉成像常规方法和传统冠状动脉造影术进行比较。结果 40例患者共120支冠状动脉中,92%(110/120)的冠状动脉可行仿真内镜成像;仿真内镜判断有意义的冠状动脉狭窄正确率为85%(41/48);常规CT冠状动脉成像不能判断的9处严重钙化,仿真内镜显示为显著或高度狭窄;4枚冠状动脉支架内和3支桥血管仿真内镜显示通畅。结论仿真内镜可立体显示正常和病变冠状动脉腔内情况,是CT冠状动脉成像后处理方法的的重要补充。
[Objective] To explore the potential clinical value of virtual endoscopy in detecting coronary artery lesions.[Methods] Forty patients underwent dual-source CT coronary angiography.Virtual endoscopies were simulated in 120 coronary arteries using the Fly-through software,with routine imaging post-processing methods of CT coronary angiography and conventional coronary angiography as the reference standard.[Results] Virtual endoscopies of 92%（110/120） major coronary artery were successfully performed with good image quality,and the accuracy of virtual coronary angioscopy was 85%（41/48） for detecting hemodynamically significant stenoses confirmed by conventional coronary angiography.Using virtual coronary angioscopy,9 severe calcified coronary arteries were identified as significant or severe stenoses,while unable to estimate by routine CT coronary angiography.Virtual endoscopies of intracoronary stents（n=4） or bypass grafts（n=4） were patency.[Conclusions] Endoscopy of coronary arteries using dual-source CT allows comprehensive 3-dimensional delineation of the vessel lumen,and can be used as an important complement to the routine post-processing methods of CT coronary angiography in some cases.
