| 目的 评价心肌首过灌注磁共振成像技术对肥厚型心肌病(HCM)心肌缺血的诊断作用。 方法 对21例肥厚型心肌病患者,行MR心脏形态学及功能学检查,并进行MR心肌灌注检查,随后对心肌灌注参数进行分析,同时对比分析心功能变化。 结果 局部心肌最大信号强度增加值(SIm)减低9例,其中合并心内膜下缺血3例;灌注阳性组与阴性组相比较,左室短轴缩短率及局部室壁增厚率明显下降。 结论 MR心肌首过灌注成像能够准确地判断肥厚型心肌病的缺血改变,磁共振成像技术可以多方面对肥厚型心肌病进行评价。 |

| Objective To access the diagnostic value of magnetic resonance first-pass perfusion imaging in hypertrophic cardiomyopathy (HCM) with myocardial ischemia. Methods Twenty-one patients with HCM were studied with gadolinium-enhanced ultrafast,magnetic resonance first-pass imaging and cine-MRI. The parameter related to perfusion and the function information were analyzed and compared statistically. Results Maximal signial intensity increase (SIm) of 9 patients were lower; subendocardial ischemia in 3 patients was observed. Patients with a positive result showed lower left ventricular fractional shortening and left ventricular wall thicking than those of patients with a negative result. Conclusion Magnetic resonance first-pass perfusion imaging has high sensitivity in judging myocardial ischemia. MRI may be the most useful method to evaluate HCM. |
