| 目的 探讨磁共振对于孤立性心肌致密化不全的临床诊断价值。方法 利用西门子1.5T磁共振机检查9例有不同临床症状的心脏病患者以进一步观察心内结构。结果 在9例患者中,磁共振清晰辨别出不同部位和程度的心肌致密化不全病变,其特征性表现为显著的小梁化心肌及深入到室壁内的小梁间隙;尤其是对于累及左室前侧壁和心尖部的病变,磁共振能较超声心动图提供更明确的形态显示和更高的空间分辨率。结论 磁共振提高了心肌致密化不全的诊断率,是超声心动图检查的有效补充和替代方法。 |

| Objective To investigate the clinical value of magnetic resonannce imaging (MRI) in the diagnosis of isolated noncompaction of ventricular myocardium (INVM). Methods Nine patients presented with various symptoms suggesting heart disease underwent cardiac MRI examinations with 1.5 Teslas magnetom scanner (Siemens) for exactly morphologic observation. Results MRI discriminated clearly the variable localization and degree of prominent trabeculations and deep intramyocardial recesses typical of INVM, especially in demonstrating the lesions involving the anterolateral wall and apical segment of left ventricle, with better visualization and spacial resolution compared to echocardiography. Conclusion MRI is an effective adjunct to echocardiography in diagnosis of INVM with higher clinical accuracy. |
