The detectability of coronary diagonal (Dx) branch disease in 24 patients (16 with myocardial infarction, 8 with angina pectoris; mean age of 56) with other branch (left anterior descending branch [LAD], left circumferential branch [LCX], or right coronary artery [RCA]) diseases was reviewed with 201TlCl exercised myocardial planar and SPECT images. In Dx branch disease with LAD #7 lesion (n = 10), Dx perfusion abnormality was detected in planar and SPECT images in 3 (30%) and 8 patients (80%), respectively. In Dx branch disease with LCX lesion (n = 7), Dx perfusion abnormality was detected in planar and SPECT images in 3 (43%) and 4 patients (57%), respectively. In Dx branch disease with RCA lesion (n = 7), Dx perfusion abnormality was detected in only 1 (14%) and 2 patients (29%), respectively. In conclusion, SPECT is a useful modality for detecting Dx branch disease, but it is sometimes hard to detect Dx branch disease with LCX and RCA lesions.
对24例患有其他分支（左前降支[LAD]、左旋支[LCX]或右冠状动脉[RCA]）疾病的患者（16例心肌梗死，8例心绞痛；平均年龄56岁），利用201TlCl运动心肌平面和SPECT图像，回顾性分析冠状动脉对角支（Dx）病变的可检测性。在伴有LAD #7病变的Dx分支病变患者（n = 10）中，平面图像和SPECT图像中分别有3例（30%）和8例（80%）检测到Dx灌注异常。在伴有LCX病变的Dx分支病变患者（n = 7）中，平面图像和SPECT图像中分别有3例（43%）和4例（57%）检测到Dx灌注异常。在伴有RCA病变的Dx分支病变患者（n = 7）中，平面图像和SPECT图像中分别仅有1例（14%）和2例（29%）检测到Dx灌注异常。总之，SPECT是检测Dx分支病变的一种有用方法，但有时很难检测到伴有LCX和RCA病变的Dx分支病变。
