心肌灌注斷層掃描檢查結果分析及建議-心臟血管專科

心肌灌注断層掃描檢查？

醫師好：回診時，醫師已開藥，想詢問是否先吃藥即可，後續心導管有症狀再去做呢？
報告如下，謝謝您-------Myocardial Perfusion Study-------------------------------- IMAGE FINDINGS: The Technecium-99m MIBI myocardial perfusion SPECT scintiphotos at 40 minutes after intravenous dipyridamole 0.56mg/kg pharmacologic stress and earlier 4 hours rest redistribution revealed ’MEDIUM’ reversible perfusion defect in the mid-to-apical anterior wall (30~40%---〉20%) of the left ventricle during stress phase with recovery of perfusion after rest redistribution. Polar map showed reversible changes in the LAD territory. IMPRESSION: 1. MODERATE Myocardial ischemia in the mid-to-apical anterior wall, the LAD territory of the left ventricle. 2. Advise correlation with other clinical findings. Terms in the impression of severity for CAD by decreased radioactivity: Scar:80%, Severe:60%, Moderate:40%, Mild:20%. ---------Ejection fraction And Regional wall motion of LV----------- IMAGE FINDINGS: The radionuclide ventriculography (RNV) was performed using multi-gated acquisition (MUGA) method with Tc-99m MIBI at both rest and dipyridamole induced stress status. The ejection fraction at exercise/rest status of the left ventricle (LVEF) were 67%--〉70% (normal 〉 50 %). The global and regional wall motion at exercise/rest status both looks normal. IMPRESSION: 1. Preserved stress And preserved rest LVEF. 2. No regional wall motion abnormality noted. Ref. of the LVEF by Multi-gated Blood Pool Analysis (MUGA) method is 〉50%.
