Abstract「要旨」心筋SPECT展開図表示を用いて罹患冠動脈の支配領域を詳細に検討し, 新たに心尖部表示を加味した展開図表示の開発を行った. 冠動脈支配領域については, 各冠動脈1枝病変の典型例(右冠動脈12例, 左前下行枝24例, 左回旋枝13例, 対角枝5例)をそれぞれ加算し, 正常パターンで標準化したものを冠動脈支配領域としてその分布様式を決定した. 心尖部表示は, SPECT長軸像の前壁, 後壁, 心尖部にROIを設定し, それを短軸像の同一部位で近似を行い, 心尖部の%カウントを求め, 従来の展開図表示とともに表示した. これらにより, 展開図表示は従来の極座標表示に比べて罹患冠動脈病変の部位, 拡がりがより正確に示され, 詳細な冠動脈支配領域の区分が得られた. また心尖部情報を加味することにより, 左前下行枝障害の検出率が向上し, 右冠動脈障害の正診率も改善された.

AbstractCoronary artery terrtories were evaluated precisely by Bull's-eye and unfolded map generated from myocardial SPECT. In addition, unfolded maps including apical information were also developed. The coronary artery territories were determined by 54 cases of typical single vessel disease (more then 75% stenosis) with myocardial infarction and angina pectoris. There were 12 of right coronary artery disease, 24 of left anterior discending coronary artery disease, 5 of diagonal coronary artery disease, and 13 of left circumflex artery disease. Each diseased region was summed and normalized using the standard pattern (21 cases of normal male and 13 cases of normal female). Apical information was simply obtained using the anterior and posterior count from short and long axial image. Then, their data were added to the unfolded map. In conclusion, unfolded map was proven to be useful for the determination of coronary artery territory, since this map expressed the extent and site of myocardial damage precisely compared to Bull's-eye. The unfolded map to contain the apical information was also useful for the evaluation of left anterior descending coronary artery involvement.
