Planar renal scintigraphy with Tc-99m DMSA has become established as a standard diagnostic test to determine if a kidney has been scarred by infection. It has been suggested that high resolution SPECT may improve the sensitivity of detection of renal scars. To determine if it is possible to produce good quality renal SPECT with a short acquisition time, 10 adults were examined with a new multi-detector gamma camera using 8 minute, 16 minute, and 32 minute acquisitions. The number of defects seen (N = 16) with an 8 minute acquisition was not significantly different from the defects (N = 15) seen using a 16 minute and a 32 minute acquisition. In adults when imaging with a multi-detector gamma camera there was no clinical advantage in using an acquisition of longer than 8 minutes.
使用锝-99m二巯基丁二酸（Tc-99m DMSA）进行的平面肾闪烁显像已成为确定肾脏是否因感染而形成瘢痕的标准诊断测试。有人提出，高分辨率单光子发射计算机断层扫描（SPECT）可能会提高肾瘢痕检测的敏感性。为了确定是否有可能在短采集时间内获得高质量的肾脏SPECT，使用新型多探测器伽马相机对10名成年人进行了检查，采集时间分别为8分钟、16分钟和32分钟。8分钟采集时发现的缺损数量（N = 16）与16分钟和32分钟采集时发现的缺损数量（N = 15）相比，差异无统计学意义。在成年人中，使用多探测器伽马相机成像时，采集时间超过8分钟并无临床优势。
