Twenty-one patients with ischemic heart disease were studied by resting 99mTc-methoxyisobutyl isonitrile (MIBI) gated SPECT images using a 3 head rotating gamma camera (Picker/Shimadzu: PRISM 3000). The data were acquired over 360 degrees in 20 (x 3) steps, each of which was 70 beats. The systolic wall thickening index (%WT) was calculated as (ES count-ED count/ED count x 100), using the circumferential profile analysis of ED and ES short axial images. The %WT was correlated well with LVEF obtained from contrast ventriculography (r = 0.85, n = 17). By using high speed (3 head) rotating gamma camera, we have shortened the time of collecting MIBI gated SPECT data, and this method can provide useful information on ventricular function.
采用三头旋转γ相机（Picker/Shimadzu：PRISM 3000），通过静息状态下的99mTc-甲氧基异丁基异腈（MIBI）门控单光子发射计算机断层扫描（SPECT）图像对21例缺血性心脏病患者进行了研究。数据在360度范围内以20（×3）步进行采集，每步采集70个心动周期。收缩期室壁增厚指数（%WT）通过舒张末期（ED）和收缩末期（ES）短轴图像的圆周轮廓分析，按照（ES计数 - ED计数/ED计数×100）进行计算。%WT与对比心室造影获得的左心室射血分数（LVEF）相关性良好（r = 0.85，n = 17）。通过使用高速（三头）旋转γ相机，我们缩短了采集MIBI门控SPECT数据的时间，并且该方法能够提供有关心室功能的有用信息。
