目的探讨双源CT冠状动脉成像中壁冠状动脉的诊断价值。方法收集424例临床怀疑冠心病或确诊冠心病患者的冠状动脉螺旋CT图像,统计壁冠状动脉的显示率及CT表现。结果在424例患者中,壁冠状动脉的检出率为12.3%,表现为局部冠状动脉走行于心肌内,部分血管直径稍微狭窄。结论双源CT是一种无创、优良的冠状动脉成像方法,可以很清晰的显示冠状动脉的解剖变异,准确的诊断壁冠状动脉。
Objective To investigate the diagnostic value of wall coronary arteries in double-source CT coronary angiography. Methods A total of 424 patients with suspected coronary heart disease or diagnosed coronary heart disease were collected from patients with coronary artery disease. The images of coronary arteries and CT findings were collected. Results Among the 424 patients, the detection rate of wall coronary arteries was 12.3%. The performance of local coronary arteries was in the myocardium, and some of the vessels were slightly stenosed. Conclusion Dual-source CT is a noninvasive and excellent method of coronary angiography. It can clearly show the anatomic variation of coronary arteries and accurately diagnose the wall coronary arteries.
