目的评估MRI心肌灌注及延迟增强对心肌梗塞的诊断价值.方法 52例疑诊心肌梗塞病例进行心脏MRI检查,男性41例,女性11例;平均年龄54.4岁,年龄范围:23～83岁.所有病例先后行FIESTA、心肌首过灌注及心肌延迟扫描检查.结果 20例患者表现为首过灌注出现充盈缺损,可见延迟增强;1例患者出现首过充盈缺损,无延迟强化:31例既无首过充盈缺损,也无延迟强化.MRI诊断心肌梗塞的敏感性为90%,特异性为93.75%,准确性为92.31%.结论 MRI首过灌注及延迟增强扫描对心肌梗塞的诊断具有较高的敏感性和特异性.

Objective To evaluate the diagnostic value of myocardial infarction with MRI myocardial perfusion and delayed enhancement. Methods FIESTA(Fast Imaging Employing Steady-state Acquisition),first-pass enhancement (FPE) and delayed enhancement (DE) magnetic resonance (MR) images were obtained m 52 patients (41 men, 11 women; mean age 54.4 years; range: 23～83years). Results Filling defect on FPE and delayed enhancement signs were observered in 20 cases,tilting defect but no delayed enhancement in one case,no filling defect and delayed enhancement in 31 cases. The sensitivity,specificity and accuracy of myocardial infarction diagnosis using MR imaging is 90%, 93.75% and 92.31% respectively. Conclusion There are high sensitivity and specificity in diagnosing myocardial infarction with FPE and DE.
