Fluorodexyglucose SPECT in acute myocardial infarction: case report

We report a 50-year-old woman with a recent myocardial infarction in whom a myocardial perfusion single photon emission computed tomography (SPECT) wi th Thallium(201) was done simultaneously with a F18-fluordeoxyglucose (FDG) SPECT to study glucose metabolism. Myocardial infarction was located in th e anteroseptal and apical regions and an echocardiography, done at the seco nd day of evolution, showed a septo-apical hypokinesia. On the tenth day, a coronary angiography showed a critical lesion of the anterior descending c oronary artery and an angioplasty with stent placement was performed on the next day. On the twelfth day, a resting, redistribution Tl-201 SPECT to st udy viability and a FDG-SPECT with a dual head high-energy collimator camer a were done. Images, acquired 45 min after injection, were analyzed visuall y. In anterior and medial apical sectors, discordance between flux and disa ppeared three month after revascularization (Rev Med Chile 2000; 128 1019-2 3).
