【摘要】：目的评价磁共振心脏成像在限制性心肌病(RCM)诊断中的应用价值。方法搜集2010年12月至2013年12月在本院就诊的12例RCM患儿为病例组,10名正常儿童为对照组。病例组和对照组均行心脏MRI检查,使用美国GE 1.5 T Signa Horizon MR扫描仪及8通道心脏线圈。分析RCM的影像学表现,测量所得心功能指标,分析心肌延迟强化情况。结果与对照组比较,病例组患儿均表现为双心房扩大,上下腔静脉及门静脉扩张;双心室舒张功能受限;心室腔大小正常或略缩小,心室壁厚度正常,心室收缩功能正常或轻度减低。其中2例患儿在心肌延迟增强检查时出现弥漫性内膜下心肌的延迟强化。结论磁共振心脏成像能反映出RCM患儿心脏结构及功能的改变,清晰地显示病变的程度及范围,是目前诊断RCM的一项特异且敏感的无创性检查手段,应该在临床上常规开展。
[Abstract]:Objective to evaluate the value of magnetic resonance cardiography in the diagnosis of restrictive cardiomyopathy (RCM). Methods from December 2010 to December 2013, 12 patients with RCM were selected as case group and 10 normal children as control group. Cardiac MRI examination was performed in both the control group and the control group. GE 1.5T Signa Horizon Mr scanner and 8-channel cardiac coil were used to analyze the imaging manifestations of RCM, to measure the cardiac function and to analyze the delayed enhancement of myocardium. Results compared with the control group, the children in the case group showed biatrial enlargement. Dilation of inferior and inferior vena cava and portal vein; limitation of biventricular diastolic function; normal or slightly smaller ventricular lumen, normal wall thickness, The ventricular systolic function was normal or slightly decreased. Two of them had diffuse subendocardial myocardial delayed enhancement during myocardial delayed enhancement. Conclusion Mr cardiography can reflect the changes of cardiac structure and function in RCM children. Clearly showing the extent and scope of the lesions is a specific and sensitive noninvasive method for the diagnosis of RCM, which should be carried out routinely in clinical practice.
