64排螺旋CT冠状动脉成像检查对心肌桥诊断的应用价值

目的：探讨64排螺旋CT冠状动脉成像（CTA）检查对心肌桥诊断的应用价值。方法：回顾性分析300例冠状动脉CTA患者，评估心肌桥的发生率、位置、长度、心肌厚度及壁冠状动脉近段和远段血管的形态。结果：心肌桥共检出82例（95段），检出率为27．3％，发生在前降支中段73处，占79-3％（73／95），心肌桥厚度为0．4-11．2mm，平均厚度为1．7mm，壁冠状动脉长度为13mm-52mm，平均22mm。结论：64排螺旋CT冠状动脉成像能清晰准确显示壁冠状动脉与心肌的解剖关系，对心肌桥的检出率高，是确诊心肌桥的首选检查方法。

Applicationg Value of Myocardial Bridge Diagnosis on 64- row Spiral CT

Objective： Discussion of 64 row spiral CT coronary artery imaging （ CTA ） examinations for diagnosis of myocardial bridge. Methods： A retrospective analysis of 300cases of coronary artery in patients with CTA, assessment of myocardial bridge of the incidence, location, length, thickness and wall myocardial coronary artery proximal and distal vascular morphology. Results： Myocardial bridge were detected in 82cases （95）, the detection rate is 27.3%, occurring in the anterior descending73, accounted for 79.3% （73/95）, myocardial bridge a thickness of 0.4 tol 1.2mm, average thickness of 1.7mm, mural coronary artery length is 13mm- 52mm, the average 22ram.Conclusion： 64-row spiral CT coronary artery imaging can clearly display the mural coronary artery and myocardial anatomy relationship of myocardial bridge, high detection rate, myocardial bridge is diagnosed first examination method.
