摘要
目的探讨门控心肌灌注显像对病毒性心肌炎的诊断价值。方法对38例病毒性心肌炎进行门控99mTc甲氧基异丁基异腈(MIBI)心肌显像。结果门控99mTc MIBI心肌显像异常者28例,占心肌炎患者的74%(28/38)。其中放射性分布Ⅱ度(明显放射性分布稀疏区)24例,占86%;Ⅲ度放射性分布缺损区4例,占14%。病灶呈Ⅰ型单灶性损害3例,占11%;Ⅱ型多灶性损害21例,占75%;Ⅲ型大面积损害4例,占16%。结论门控心肌灌注显像能较直观地表现病变心肌的部位、形态、范围和程度,为病毒性心肌炎的诊断提供较为敏感的检查手段。
Objective To investigate the diagnostic value of gated myocardial perfusion imaging in viral myocarditis (G-MPI).Methods 99mTc-MIBI G-MPI was performed on 38 patients with viral myocarditis. Results Twenty-eight(28/38, 74%) patients with abnormal 99mTc-MIBI G-SPECT were discovered in those viral myocarditis, including 24(24/28,86%)of grade II distribution (obviously decreased radioactivity) and 4(14/28, 14%) of grade III distribution. In all the 28 cases of lesions, 3(11%) were single-focal (model I), 21(75%) were multi-focal (model II) and 4(16%) suffered large area (model III). Conclusion G-MPI could intuitionally reveal the location, morpha, range and degree of pathological myocardium, and could act as a sensitive detection means for viral myocarditis.
