^(99m)Tc-MIBI心肌断层显像对冠心病诊断的价值

Evaluation of ^(99m)Tc-MIBI Myocardial Tomography imaging for Diagnosis of Coronary Heart Disease

本文报告经临床、心电图及亚极量心电图负荷试验、酶学化验等综合判定而确诊为冠心病、冠心病合并高血压和心肌梗塞患者101例,通过^(99m)Tc-MIBI 心肌断层显像,对冠心病的检出率为70%～80%.运动负荷心肌断层能提高检出率,而心电图亚极量负荷试验检出率为63.8%,说明核素心肌断层显像是一项诊断冠心病的灵敏度高、特异性强的无创伤性检查。

^(99m)Tc-MIBI myocardial tomography imaging was obtained from 101 cases using Sopha Medical SPECT system, including 38 patients with coronary heart disease, 33 with coronary heart disease combined with hypertension and 30 with myocardial infarction diagnosed on clinical symptoms and signs,ECG exercise ECG (treadmill test) and laboratory study. The results showed that the sensitivity of myocardial imaging for detecting coronary heart disease was 70%～80% at rest, increasing with stress. Whereas the sensitivity of exercise ECG was 63. 8%. Radionuclide myocardial imaging is a method of noninvasion, and is more sensitive and specific than excercise ECG in detecting coronary heart disease with patients either at rest or on stress test.
