Tl-201 chloride 施打後心臟影像檢查結果分析-內科

煩請醫師幫我看一下報告，是否嚴重？謝謝？

Clinical history : r/o CAD Procedures : Following the intravenous injection of 2 mCi of Tl-201 chloride under stress condition caused by Dipyridamole 0.56mg/kg iv, stress SPECT imaging of the heart was performed 5 min later. Aminophylline 50 mg was also administered iv before imaging. After a period of 3-4 hrs, the patient returned to the lab and was then imaged in a similar fashion while at rest. Findings : 1. Moderately decreased perfusion to the inferoseptal wall, mildly to moderately to the apex and inferior wall on stress images, which shows good refilling on redistribution images (reversible defects). 2. Moderately to severely decreased perfusion to the mid/basal septal wall on stress images, which shows partial refilling on redistribution images (partially reversible defects). Conclusions : 1. Likely moderate CAD involving the inferoseptal wall. 2. Likely mild to moderate CAD involving the apex and inferior wall. 3. Likely moderate to severe CAD combined with some extent of scarring involving the mid/basal septal wall. 4. Further management is recommended.
