| Abstract | 「I. 緒言」従来, 虚血性心疾患の診断に用いられている種々の方法では虚血の程度, 部位, 拡がりを確実に把握できないことがまれでない. これを補うものとして核医学的診断法が導入された. そのうち心筋イメージングに関しては43K, 86Rb, 131Csをはじめ多くの放射性医薬品が用いられてきたが, エネルギーおよび半減期などの点で必ずしも適当ではなく, 広く用いられるに到らなかった. 1970年にKawanaらは201Tlによる心筋イメージングの可能性を報告し, 以来, その優れた物理的諸性質により脚光を浴びた. 筆者らは201Tlにより, 主として心筋梗塞の部位, 拡がりの診断の可能性をシンチグラフィー, カラーディスプレイ, 9点スムージングにより検討し, また関心領域(以下ROI)の設定による定量的評価を試みたので以下に報告する. 「II. 対象及び方法」対象: 川崎医科大学附属病院に入院又は通院中の患者のうち, 非心筋梗塞11例および心筋梗塞13例である. |

| Abstract | Eleven cases without myocardial infarction and 13with myocardial infarction were given intravenous injection of 1.5-2.0 mCi of 201Tl, and the images were taken with a PHO/gamma HP camera connected to the color display apparatus-CDP-1. Regions of interest corresponding to the myocardial and non myocardial regions were selected with CDP-1. In the anterior view of the scintiphotos in non infarction cases, the left ventricular wall appeared as U or O or solid-ovoid in shape, indicating a decrease of the activity at the apex. In the cases of suspected cardiac amyloidosis, atrial septal defect and mitral with tricuspid insufficiency, the right ventricular wall as well as the left ventricular wall was delineated and the ratio of radioactivity of the left to right walls in these cases was 1.42, 1.21 and 1.00 respectively. The anterior wall infarction revealed decreased activity in the anterior, left anterior oblique and left lateral views. The posterior wall infarction showed such a decrease in the left anterior oblique and lateral views. The posteroinferior infarction was displayed in the anterior and left lateral views. In the case of a large infarction at the posterior wall or apex it presented an inverse U shape. The ratio of activity of normal region to infarcted region was 1.44 and that of normal to the lung and that to the ventricular cavity were 3.07 and 1.48 respectively. The ratio of the infarcted region to the lung and that to the ventricular cavity were 2.19and 1.40 respectively. Hence in evaluating the myocardial imaging subjectively, more accurate findings can be attained from the ratios of cardiac muscle to lung. |
