摘要
目的比较缺血性和非缺血性心脏病患者心肌病变的磁共振心肌延迟强化的影像学特征。方法回顾性分析了25例有心肌延迟强化患者的磁共振成像特点及相应临床表现。结果25例患者中,19例为缺血性心脏病,磁共振延迟强化区域为透壁和心内膜下非透壁心肌;2例为肥厚性心肌病,延迟强化位于肥厚的心肌内部,呈不规则条片状;1例为扩张性心肌病,表现为心肌内部弥漫小灶强化区;2例为限制性心肌病,表现为左、右心室心内膜下条带状强化,伴有左心室和右心房附壁血栓;1例为左心室外侧壁占位性病变,表现为片状强化。结论磁共振心肌延迟强化并非心肌梗死的特异性表现,鉴别延迟强化的非缺血性心脏病病因有赖于密切结合临床病史,心肌延迟强化影像表现有一定的提示作用。
Objective To compare the imaging characteristics of magnetic resonance(MR) delayed enhancement between ischemic and nonischemic myocardial diseases.Methods We retrospectively analyzed the imaging and clinical characteristics of 25 patients who had MR delayed enhancement.Results Among the 25 cases,19 cases were ischemic heart diseases,in which the delayed enhancement was subendocardium,nontransmural or transmural;two cases were hypertrophic cardiomyopathy,in which the delayed enhancement was midwall in the h...
