目的 :探讨99mTc -MIBI心肌显像对心肌炎患儿心肌损害的检测及评估价值。方法 :对 2 2例疑似心肌炎和 40例心肌炎患儿进行99mTc-MIBI心肌断层显像 ,采用节段记分法对结果进行分析。结果 :疑似心肌炎组有 5例共 8个节段 (4.0 % )显像异常 ;心肌炎组中 30例共 6 7个节段 (18.6 % )显像异常 (P <0 .0 0 1)。心肌炎组中 11例伴心律失常的患儿心肌显像全部异常 (P <0 .0 0 1)。结论 :99mTc-MIBI心肌断层显像对心肌炎患儿心肌损害检测及轻重程度的评估有较好的实用价值。
Objective: To investigate the detection and evaluation of 99mTc-MIBI myocardial imaging in children with myocarditis. Methods: Twenty-two children with suspected myocarditis and 40 children with myocarditis were subjected to 99mTc-MIBI myocardial imaging, and the results were analyzed by segment scoring method. Results: There were 5 cases of suspected myocarditis in 8 segments (4.0%). The myocarditis group had a total of 67 segments (18.6%) with imaging abnormalities (P <0.01). Myocarditis group of 11 patients with arrhythmia in myocardial imaging were all abnormal (P <0.001). Conclusion: 99mTc-MIBI myocardial perfusion imaging in children with myocarditis myocardial damage detection and severity assessment has good practical value.
