【摘要】：目的探讨99 Tcm-MIBI心肌灌注显像对心肌桥的临床价值。方法回顾性分析105例冠状动脉CTA诊断为心肌桥并接受运动及静息99 Tcm-MIBI心肌灌注显像的患者资料,分析心肌灌注显像结果,并与冠状动脉CTA结果进行比较。结果 105例心肌桥患者中,根据Nobel分级法,Ⅰ级狭窄21例,Ⅱ级狭窄24例,Ⅲ级狭窄60例;其中60例出现心肌缺血改变。缺血组与非缺血组心肌桥患者冠状动脉CTA显示狭窄程度的差异有统计学意义(χ2=61.731,P0.001)。不同部位心肌桥血管支发生异常灌注的差异无统计学意义(χ2=3.588,P=0.166)。结论 99 Tcm-MIBI心肌灌注显像能够用于评价冠状动脉心肌桥。
[Abstract]:Objective to evaluate the clinical value of 99 Tcm-MIBI myocardial perfusion imaging in myocardial bridge. Methods the data of 105 patients with myocardial bridge diagnosed by coronary artery CTA and receiving exercise and rest 99 Tcm-MIBI myocardial perfusion imaging were analyzed retrospectively. The results of myocardial perfusion imaging were compared with that of coronary artery CTA. Results according to Nobel classification, there were 21 cases of grade 鈪，
