| Abstract | 「要旨」 回転型ガンマカメラによる心筋 ECT の体軸横断画像データから, 左室長軸に直交する左室短軸断層像および長軸に平行な右前斜位断層像の2種類の任意断面像を再構成し, 心筋梗塞診断における有用性を検討した. ファントム実験および臨床例において任意断面像再構成による左室短軸断層像は, 7ピンホール法による断層像と視覚的に類似し, 定量的には欠損検出能は7ピンホール法より優れていた. 左室長軸に平行な右前斜位断層像は, 左室心筋を広く観察でき, 同方向からの局所壁運動能との対比に有用であった. またROC解析の結果から, 任意断面像を含めることにより, 心筋梗塞の診断率が向上する可能性が示唆された. 心軸に合わせた任意断面像再構成は, 心筋梗塞診断に有用な方法と思われる. |

| Abstract | [Summary] Two kinds of arbitrary tomographic plane images that actually sliced the heart parallel (RAO tomographic plane) and perpendicular to the long axis of the left ventricle were reconstructed from the data of continuous transaxial tomographic sections of Tl-201 ECT with a rotating gamma camera. The arbitrary tomographic plane images that sliced the heart perpendicular to the long axis of the left ventricle resembled to tomographic images by the seven-pinhole technique, but they showed higher detectability of hypoperfusion area by circumferential profile analysis than the seven-pinhole method. The RAO tomographic plane images were useful to compare with regional left ventricular wall motion in the same direction. In a clinical evaluation of 50 patients, the result of ROC analysis showed that arbitrary tomographic plane images were more useful to detect myocardial infarction than conventional transaxial, sagittal and frontal tomographic plane images. |
