A significant improvement in cardiovascular nuclear medicine has resulted from imaging the beating ventricles by motion-picture display of the intraventricular distribution of 99mTc albumin during 16 phases of the cardiac cycle. We have now begun to make "fast-motion" pictures of other body functions, including the cerebral circulation, pulmonary ventilation, biliary excretion, and renal blood flow. Data obtained over minutes, hours or days are compressed into 16 frames per second. These "compressed-time" images improve our perception of regional dysfunction, and the degree of certainly of our diagnoses. They do so by eliminating the blurring inevitably produced in the usual static images of moving structures, such as the heart, and by revealing small changes in regional function.
通过在心动周期的16个时相动态显示99mTc白蛋白在心室中的分布来对跳动的心室进行成像,心血管核医学取得了显著进展。我们现在已开始制作其他身体功能的“快动作”图像,包括脑循环、肺通气、胆汁排泄和肾血流。在数分钟、数小时或数天内获取的数据被压缩为每秒16帧。这些“压缩时间”图像改善了我们对局部功能障碍的感知,以及诊断的确定程度。它们通过消除在移动结构(如心脏)的常规静态图像中不可避免产生的模糊,并揭示局部功能的微小变化来做到这一点。
