Abstract

A 60-year-old man with isolated noncompaction of the ventricular myocardium was evaluated by magnetic resonance imaging (MRI), which clearly showed excessively prominent trabeculations and deep intertrabecular recesses that correlated well with the findings on echocardiography and contrast enhanced computed tomography. On the T2-weighted and contrast enhanced MRI scans, the noncompacted myocardium was separated into 2 layers: a subendocardial and an endocardial layer. A difference in signal intensity may reflect myocardial damage that leads to ventricular dysfunction or arrhythmia.

摘要

一名60岁孤立性心室心肌致密化不全男性患者接受了磁共振成像（MRI）评估，结果清晰显示出过度突出的肌小梁和深陷的小梁间隐窝，这与超声心动图及对比增强计算机断层扫描的结果高度相关。在T2加权和对比增强MRI扫描中，致密化不全的心肌被分为两层：心内膜下层和心内膜层。信号强度的差异可能反映了导致心室功能障碍或心律失常的心肌损伤。
