^(99m)TC-MIBI灌注断层显像与动态心电图联合诊断病毒性心肌炎

^(9m)TC-MIBI myocardial perfusion imaging with ambulatoury electrocardiography for diagnosis of viral myocarditis

目的探讨99mTC-MIBI灌注断层显像(ECT)与动态心电图联合检查对病毒性心肌炎的诊断价值。方法所有病人均做ECG、Holter、9mTC-MIBI灌注断层显像检查、心肌酶和心肌肌钙蛋白的检测,比较各项指标的阳性率。结果显示动态心电图的阳性检出率高于心电图,9mTC-MIBI灌注断层显像的阳性检出率高于心肌肌钙蛋白或心肌酶。9mTC-MIBI灌注断层显像与动态心电图联合检查的阳性检出率高于单用9mTC-MIBI灌注断层显像或Holter。结论联合应用9mTC-MIBI灌注断层显像与动态心电图检查有助于对病毒性心肌炎的诊断,尤其是不典型病例。

Objective To explore the value of ambulatoury electrocardiography with ^99mTC-MIBI myocardial perfusion imaging for diagnosis of viral myocarditis. Methods ^99mTC-MIBI myocardial perfusion imaging,ECG,Holter ,CK-MB,eTnI were examined for 70 patients with viral myocardifis. The value of anrbulatoury, electrocardiography and ^99mTC-MIBI-myocardial perfusion imaging for diagnosis of viral myocarditis were analyzed. Results The abnormality rare suggested viral myocardifis for ambulatottry eleetrocardiography,^99mTC-MIBI myocardial perfusion imaging and ambulatoury electrocardiography with ^99mTC-MIBI myocardial perfusion imaging was 67.14% ,78.57%, 92.86% respective. Conclusion The ambulatoury electrocardiography with ^99mTC-MIBI myocardial perfusion imaging is more valuable for diagnosis of viral myocardius.
