本文对２０例正常人与３１例扩张型心肌病（ＤＣＭ）进行核素心血地显像，结果显示：ＤＣＭ，患者左心室腔异常扩大，室壁活动呈全心性弥漫性明显低下或近于消失；左室振幅灰度明显降低，双室时相灰度绝对不均，相角程异常增宽，平均１４１℃左右；左室收缩及舒张功能的各项指标均严重下降，且具有一定的变化特点。该显像方法可用子ＤＣＭ的诊断。
In this paper, 20 patients with normal and 31 patients with dilated cardiomyopathy (DCM) radionuclide imaging, the results showed: DCM, patients with abnormal left ventricular cavity expansion, ventricular wall was diffuse significantly lower or nearly full Disappeared; gray scale of left ventricular amplitude was significantly reduced, the absolute gray level of two-chamber phase was absolutely unbalanced, the phase angle range was abnormal widened, with an average of about 141 ℃; indexes of left ventricular systolic and diastolic function both declined severely, Change characteristics. This imaging method can be used to diagnose sub-DCM.
