| Abstract | 「要旨」東芝DAP 5000Nを用いて左心機能解析法を検討した. In vivo標識99mTc-赤血球を用い, データは, 平衡時心プール像を心電図同期法により, リストモードで収集した. 左室駆出率と最大収縮速度, 最大拡張速度に影響を与える因子として, 左室関心領域の大きさおよびバックグラウンド値について検討した. これらの値は通常の変動の範囲内では, 左室関心領域の大きさにより±4%以内, バックグラウンド値により±7%以内であり, 再現性は良好であった. 種々の心疾患を含む患者27名について, 左室壁運動のfunctional imageとしてstroke volume像, ejection fraction像, paradox像を作製し検討した. これらのfunctional imageは, 従来の左室壁運動の実時間表示法, 左室輪郭表示法に比して三次元的な情報を含むものであり, 左室壁異常運動の評価に有効な方法と考えられた. |

| Abstract | [Summary] The method of left ventricular analysis with Toshiba DAP 5000N is developed. Following in vivo labeling of red blood cells with Tc-99m, data were obtained by equilibrium method, utilizing Anger scintillation camera with high resolution collimator. The camera detector was positioned in the modified left anterior oblique projection. The size of the region of interest of left ventricle and the setting of background were studied as to whether these facters practically influence the reproducibilities of the ejection fraction, systolic dV/dt and diastolic dV/dt. The results showed that reproducibilities of these parameters were reasonably good. Functional images of the regional left ventricular wall motion, i.e. stroke volume image, ejection fraction image and paradox image were produced in 27 patients with or without ischemic heart disease. These functional images were considered to be more useful in the evaluation of the left ventricular asynergy than the conventional movie mode display and superimposition of the left ventricular perimeters. |
