摘　　要：目的 :探讨放射性核素心肌断层显像诊断各种病因导致儿童心肌细胞受损的临床价值。方法 :对 5例正常儿童及 75例各类心脏疾患 (分别为 :病毒性心肌炎、疑似病毒性心肌炎、原发性心肌病、先天性心脏病、风湿性心脏病及川崎病 )的儿童进行静息99Tcm 甲氧异腈 (MIBI)心肌断层显像 ,定性分析心肌内放射性分布情况 ,判断心肌病变累积的范围及程度。结果 :核素心肌断层显像显示 :正常对照组儿童心肌内99Tcm MIBI分布均匀 ;病毒性心肌炎组、疑似心肌炎组、原发性心肌病组、先天性心脏病组及其他心脏病组心肌断层显像异常的阳性率分别为 :5 4 84 % ,2 5 0 0 % ,10 0 % ,2 7 2 7%及 83 33%。结论 :放射性核素心肌断层显像对诊断小儿心肌病变是一种安全简便无创的检查方法。是评价各种病因导致儿童心肌细胞受损的可靠辅助诊断手段。Objective:To assess the value of myocardial damage caused by each cardiac diseases in children using radionuclide myocardia perfusion tomography.Method:5 normal children and 75 children with different heart diseases underwent 99 Tc m MIBI myocardial perfusion SPECT. Analyzed the myocardial distribution of 99 Tc m MIBI and estimated the damage involved in the myocardium. Result:5 normal children showed perfusion uniformity without segmental distribution. The positive SPECT imaging in each group of viral myocarditis, idiopathic cardiomyopathy, congenital heart disease and the other heart disease is 54 84%, 25 00%, 100%, 27 27%, and 83 33%. Conclusion:the radionuclide imaging is a useful noninvasive method for evaluating pathological changes of myocardium in children. It is the important examination to diagnose the myocardial damage caused by each diseases in children.
