| Abstract | 「要旨」対角枝病変による狭心症9例, 心筋梗塞4例におけるTl-201心筋SPECT像の特徴を検討した. 対角枝による虚血または梗塞所見を示す最も心基部に位置する短軸断層像における虚血または梗塞所見は-30度から30度の間に認められ, この断層像が心基部側に位置するほど対角枝の病変部位は前下行枝起始部に近付く傾向が認められた. 虚血または梗塞領域は中隔側には認められなかった. この領域の中央部における幅は5度から70度の間にあった. 虚血または梗塞領域が心尖部に達する5例の対角枝はいずれも長いか, 広く分岐し, このうち2例では心尖部全体を覆っていた. 3例では虚血領域が極めて狭く, 短かったがこれらの対角枝は冠動脈造影所見でも短かかった. Tl-201心筋SPECT像により対角枝病変の部位と当該対角枝の大きさの推定が可能と考えられた. |

| Abstract | [Summary] Noninvasive detection of coronary artery lesion of diagonal branch is important. Utility of Tl-201 myocardal SPECT images for this purpose were 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 lied between -30 degree and 30 degree and basal abnormal region was very narrow. Width of mid portion of abnormal region lied 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. |
