| 摘 要： | 目的 评估64层螺旋CT(64-MDCT)冠状动脉造影时心肌桥的检出率及临床价值.方法 回顾性分析2005年7月～2006年12月共3011例临床疑有冠心病患者的64.MDCT冠状动脉造影检查资料.结果 MDCT共检出心肌桥174例,检出率为5.8%.其中168例(96.6%)为单发心肌桥,6例(3.4%)为多发心肌桥.前降支最多见,为167例(96.0%).心肌桥长5～120 mm,平均长度30.5 mm.壁冠状动脉深度为1.3～2.8 mm,平均厚度2.3 mm.单存表现为心肌桥79例(45.4%),心肌桥合并冠状动脉粥样硬化及狭窄95例(54.6%).结论 MDCT是一种诊断心肌桥的可靠、无创性方法,可直接测量心肌桥长度、壁冠状动脉深度,同时能检出合并其他的冠脉和心脏病变,为临床治疗计划的制定提供有益的帮助.

| Abstract: | Objective To evaluate the detection rate of myocardial bridging by 64-slice spiral CT coronary angiography. Methods The data of 3011 patients with suspected coronary artery disease undergoing 64-slice spiral CT coronary angiography were collected and analyzed retrospectively. Results A total of 174 cases (5.8%) with myocardial bridging were detected by 64-slice spiral CT coronary angiography, among which 168(96.6%) had single foci of involvement and 6 (3.4%) had were multiple foci. Involvement of the left a... |
