| 目的 探讨201Tl心肌灌注显像对病毒性心肌炎的诊断价值。 方法 对168例临床确诊的心肌炎患者进行201Tl心肌灌注显像。 结果 阳性组(Ⅰ~Ⅲ度)142例;阴性组(0度)26例。阳性组中放射性稀疏Ⅰ度60例(42.25%);Ⅱ度57例(40.14%);Ⅲ度25例(17.61%)。左心室前壁受累者在阳性组中占90.14%(128/142);下后壁受累占82.39%(117/142);侧壁受累占31.69%(45/142);间壁受累占27.46%(39/142);9例静息显像左心室射血分数减低较负荷后EF减低更为明显。结论 201Tl心肌灌注显像能直观地表现病变心肌的部位、形态、范围及程度,运动或药物负荷试验,能安全、无创地增加心肌炎的检出率,是诊断心肌炎的一种敏感手段。 |

| Objective To observe the diagnostic value of 201Tl myocardial perfusion imaging (MPI) in viral myocarditis. Methods 201Tl MPI was performed on 168 patients with viral myocarditis. Results Positive group (from grade Ⅰ to Ⅲ) consisted of 142 patients. Negative group consisted of 26 patients with normal 201Tl MPI (grade 0). Sixty patients (42.25%) was grade Ⅰ, 57 patients (40.14%) was grade Ⅱ and 25 patients (17.61%) was grade Ⅲ. In the positive group, the anterior wall injury was detected in 128 (90.14%), 117 (82.39%) patients with inferoposterior wall injury, 45 (31.69%) patients with lateral wall injury and 39 (27.46%) patients with septum wall injury. Compared with rest 201Tl Gate-MPI, left ventricular ejection fraction of 9 patients decreased more obviously than in stress 201Tl Gate-MPI. Conclusion As a non-invasive method, 201Tl MPI can intuitionally reveal the location, morpha, range and degree of pathological myocardium. Being a sensitive diagnostic method, stress MPI can improve the detection rate of viral myocarditis. |
