顾性分析2011-06 ~ 2011-12 行64 层螺旋 CT 冠状动脉血管成像的 1000 例病人的 CTA 图像,对图像分别行多
平面重建(MPR)、最大密度投影(MIP)和容积重现(VR)法重建图像,并对结果进行分析、总结。 结果:1000 例
完整冠状动脉 CTA 结果中,诊断冠状动脉先天性异常起源者共36 例,发生率为3. 6%。 其中男 16 例,女 20 例,
年龄36 ~ 74 岁,平均52. 2岁。 其中左冠优势型2 例,均衡型5 例,右冠优势型29 例。 发现的冠状动脉起源异常
种类有:右冠状动脉变异 12 例(33. 3%);左冠状动脉变异 19 例(52. 8%);冠状动脉其他分支起源异常 5 例
(13. 9%)。 所有图像通过不同的重建方法可以清晰直观地显示异常血管的起始和行程。 结论:64 层螺旋 CT 冠
状动脉成像可清晰显示冠状动脉异常起源,可为心血管医师提供有价值的影像,为一种无创、安全、有效的检查
方法。

Abstract: | Objective: To investigate the 64 - slice CT coronary angiography in the diagnosis of
anomalies of the clinical value of coronary artery origin. Materials and Methods A retrospective analysis
64-slice CT coronary angiography in 1000 patients in June -December 2011 with CTA images,the
images were the multi-planar reconstruction(MPR),maximum intensity projection(MIP) and volume
reconstruction(VR)method,the results were analyzed,summarized. Results:Of 1000 cases of coronary
CTA results,diagnosis of congenital anomalies of coronary origin of a total of 36 cases,the rate was
3. 6%. Including 16 males and 20 females, aged 36 to 74 years old, average 52. 2 years old. One
advantage of type 2 cases the left coronary,balanced in 5 cases,right coronary dominant type in 29
cases. Types of anomalous origin of coronary artery found there:the right coronary artery variant in 12
cases(33. 3%);variation of left coronary artery in 19 cases(52. 8%);other branches of anomalousorigin of coronary artery in 5 cases ( 13. 9%). All images by different reconstruction methods can
clearly visualize the beginning of abnormal blood vessels and stroke. Conclusion:64-slice CT coronary
angiography can clearly show the anomalous origin of coronary arteries,can provide valuable images for
cardiologists,as a non-invasive,safe and effective method. |
