Twenty patients underwent gated synchronized 201Tl myocardial scanning (TMS). Twelve also performed a rest blood pool multigated acquisition ( MUGA ) study. A 'static' image was obtained by adding all the gated frames of the study. In this way we found the conventional static study quite unnecessary. Comparing the gated TMS to the static one revealed significantly improved resolution in the gated images and additional information concerning wall motion and myocardial thickness. Close agreement was found with results of MUGA studies of the same patients. By the addition of diastolic frames the imaging time needed to obtain improved image quality was found to be not more than 10 min per view. The exclusion of imaging time as a limiting factor for gated TMS is stressed.
20例患者接受了门控同步201Tl心肌扫描（TMS）。其中12例还进行了静息血池多门控采集（MUGA）研究。通过将研究中的所有门控帧相加获得“静态”图像。通过这种方式，我们发现传统的静态研究完全没有必要。将门控TMS与静态TMS进行比较，发现门控图像的分辨率显著提高，并且获得了有关室壁运动和心肌厚度的额外信息。与同一患者的MUGA研究结果密切一致。通过增加舒张期帧，发现获得改善图像质量所需的成像时间每个视野不超过10分钟。强调排除成像时间作为门控TMS的限制因素。
