摘要
本文分析了50例陈旧性心肌梗塞(OMI)包括10例心室壁瘤的磁共振成像(MRI)所见,并对有关诊断问题及其病理和临床意义进行了讨论,室壁限局性变薄、信号强度减低、病变部收缩期增厚率异常和节段性运动功能异常等为OMI的MRI基本征象,具有重要的诊断意义。本文提出一种在MR图像上定量分析OMI病灶大小的方法。收缩期增厚率异常作为OMI的基本征象文献上尚未见报道。
The MRI findings of 50 patients with old myocardial infarction (OMI) including ten complicated by left ventricular aneurysm (LVA) were described in the present article with discussion on the diagnosis and its pathologic and clinical implications. Focal wall thinning of the left ventricle and interventrieular septum, decrease in signal intensity of the involved segment, abnormality of systolic wall thickening percentage as well as segmental wall motion abnormality were the major MRI findings of vital importance in the diagnostic evaluation of OMI. A method for quantitative measurement of the OMI size on the MR image was also developed and described. The abnormality of systolic wall thickening percentage as one of the major sign for OMI has not been reported in the literature.
