Noninvasive detection of coronary artery lesion of diagonal branch is important. Utility of Tl-201 myocardial SPECT images for this purpose was studied in 9 patients with angina pectoris and 4 patients with myocardial infarction, in whom localized stenosis more than 75% was noted at diagonal branch. Position of basal margin of abnormal region in the coronal images lay between -30 degree and 30 degree and basal abnormal region was very narrow. Width of mid portion of abnormal region lay from 5 degree to 70 degree. Abnormal region due to diagonal branch was not noted in septal region. These results showed the utility of Tl-201 myocardial SPECT images for detecting coronary artery lesion of diagonal branch.
无创检测对角支冠状动脉病变具有重要意义。我们对9例心绞痛患者和4例心肌梗死患者进行了研究，这些患者对角支存在大于75%的局限性狭窄，探讨了铊-201心肌单光子发射计算机断层扫描（SPECT）图像在此方面的应用价值。在冠状位图像中，异常区域基底部边缘位置在-30度至30度之间，基底部异常区域非常狭窄。异常区域中部宽度在5度至70度之间。在间隔区域未发现对角支所致的异常区域。这些结果表明铊-201心肌SPECT图像在检测对角支冠状动脉病变方面具有应用价值。
