心肌灌注斷層掃描報告解讀及風險因素分析-心臟血管專科

心肌灌注断層掃描報告？

醫生您好，我做了心肌灌注断層掃描，結果如下，請問這份報告要如何解讀呢？
是否心臟有問題呢，謝謝您INDICATION: Diagnosis of coronary artery disease. CLINICAL HISTORY: Chest tightness. ECG (2025/05/07): NSR, TWI over lead III. CAD risk factors: Dyslipidemia, ex-smoker (quitted for 17 years). NUCLEAR MEDICINE STUDY: Thallium-201 myocardial perfusion imaging (MPI), dipyridamole ＆ resting. RADIOPHARMACEUTICAL: Thallium-201 3.0 mCi intravenous. (BW: 95.1 kg) PATIENT’S RESPONSE: No subjective discomfort was noted after dipyridamole stress. SCINTIGRAPHIC FINDINGS: Thallium-201 myocardial perfusion imaging was performed after standardized dipyridamole stress protocol (dipyridamole: 0.56mg/Kg, continuous IV infusion in 4 minutes) and resting state, respectively. The initial and 4-hour delayed images showed (1) slightly reversible perfusion defect in the mid-to-basal inferoseptal wall, (2) slightly decreased perfusion in the inferolateral wall, (3) normal lung uptake after stress (lung/heart ratio, stress/rest = 0.33/0.40). * Gated SPECT (QGS method, 8 frames/per cardiac cycle): (1) Post-stress LVEF = 58 %, rest LVEF = 44 % (which could be underestimated). (2) Wall motion: no obvious regional wall motion abnormality in the post-stress phase. Under standardized dipyridamole stress test, (1) attenuation artifacts or slight stress-induced ischemia in the mid-to-basal inferoseptal wall, (2) more likely attenuation artifacts in the inferolateral wall, (3) fair LV systolic function after stress (post-stress LVEF = 58%). Suggest correlation with clinical information and other studies.
