| Abstract | 「要旨」心筋梗塞領域の広がりから, その責任冠動脈の狭窄部位がどの程度推定可能か明らかにする目的で, 各冠動脈の灌流領域図を作製し, コンピュータ自動診断のプログラムを作製した. 対象は, LAD病変16例, LCX病変6例, RCA病変8例の計30例である. SPECT像より得られた10短軸断層像について, circumferential profile curveを求め, infarction mapを作製した. 各冠動脈病変について, 平均の梗塞領域を求め, 各冠動脈灌流領域図を作製した. それをもとに各冠動脈梗塞指数を求め, コンピュータ自動診断を行った. さらに, LAD病変については, 第一対角枝より中枢側病変と末梢側病変にわけて検討した. 各冠動脈梗塞指数によりコンピュータ自動診断が可能であり, また, 第一対角枝より中枢側病変と末梢側病変とでは, 心尖部から中央部にかけた側壁に差が認められ, 鑑別が可能であった. |

| Abstract | [Summary] In order to estimate coronary perfusion territory in terms of the extent of myocardial infarction, we developed a diagnostic program for perfusion territory from the territory map of each major coronary artery. We studied 30 patients with myocardial infarction: 16 patients with LAD lesion, 6 patients with LCX lesion, and 8 patients with RCA lesion. We constructed the infarction map from circumferential profile curves of 10 short axis sections of SPECT in each patient. The resultant infarct area corresponding to each of LAD, LCX and RCA lesions was used as the mean of infarct size in typical cases, and the perfusion territory map was constructed for three major coronary arteries. The infarct index based on the territory map was calculated and used for automatic determination of coronary perfusion territory. With LAD lesions, we further studied if the lesion was proximal or distal to the first diagonal branch of LAD artery. We conclude that this diagnostic program is quite useful in automatic estimation of coronary artery lesion which caused myocardial infarction, and that the lesion proximal or distal to the first diagonal branch results in whether lateral wall infarct is involved or not. |
