摘要

一位有糖尿病和高血壓病史的68歲女性已胸悶數月，最近一個月更爲頻繁、劇烈。她先接受核醫心臟掃描，發現心臟前壁有缺血變化，顯示LAD流域可能有血管阻塞。兩星期後接受雙射源電腦斷層冠狀動脈攝影，發現LAD中段有95%狹窄。由於藥物治療幫助有限，最後決定接受心導管檢查。心導管冠狀動脈攝影發現LAD近端有70%狹窄，醫師在該處放置一個支架。本案例將三種影像檢查進行臨床比較分析，結果發現鉈－201心肌灌注單光子射出電腦斷層掃描比雙射源電腦斷層心臟冠狀動脈攝影更接近心導管冠狀動脈攝影的結果。

A 68-year-old-woman with diabetes mellitus (DM) and hypertension suffered from exertional dyspnea and intermittent chest tightness for months. The symptoms got more frequent and severe. She received myocardial perfusion imaging, which demonstrate partial reversible perfusion defect in the anterior wall, revealing ischemic change and the possibility of left anterior descending (LAD) stenosis. She received dual-source CT (DSCT) coronary angiography, which revealed 95% stenosis in mid LAD artery. Due to failure of medical treatment, she received catheterization coronary angiography, which showed 70% stenosis in proximal LAD. Comparing with the results of catheterization coronary angiography, 201Tl myocardial perfusion SPECT showed better correlation than DSCT.
