采用正电子发射计算机断层扫描(ECT)同步多门控数据采集技术，获得心肌血池和心肌图像。对~(13)NH_3、~(18)F-2-氟-2-D-脱氧葡萄糖和~(11)C-碳氧基血红蛋白在正电子电子断层扫描中多次门控数据采集的可行性和要求进行了研究。给出了当在数据采集中使用心电门控时增强图像细节并促进图像解释的例子。对一系列志愿者的计数率数据的分析表明，在多重门控数据收集格式下，可以在不增加给药剂量的情况下获得多个统计上足够的图像。
Electrocardiographic (ECG) synchronized multiple gated data acquisition was employed with positron emission computed tomography (ECT) to obtain images of myocardial blood pool and myocardium. The feasibility and requirements of multiple gated data acquisition in positron ECT were investigated for 13NH3, (18F)-2-fluoro-2-D-deoxyglucose, and (11C)-carboxyhemoglobin. Examples are shown in which image detail is enhanced and image interpretation is facilitated when ECG gating is employed in the data collection. Analysis of count rate data from a series of volunteers indicates that multiple, statistically adequate images can be obtained under a multiple gated data collection format without an increase in administered dose.
