We illustrate the importance of short imaging times during gastroesophageal (GE) scintigraphy to better image GE reflux while still obtaining clinically useful gastric emptying data. While most reflux scans are comprised of 30- or 60-sec sequential images, we advocate the use of 10-sec images to maximize the signal-to-noise ratio of any radionuclide present in the esophagus. In the current case, clinically documented reflux of significant magnitude was missed during a study inadvertently performed using 60-sec frames, but subsequently detected using a 10-sec imaging protocol.
我们阐述了在胃食管（GE）闪烁扫描期间短成像时间的重要性，以便在获取临床有用的胃排空数据的同时，更好地对胃食管反流进行成像。虽然大多数反流扫描由30秒或60秒的序列图像组成，但我们主张使用10秒的图像，以最大化食管中存在的任何放射性核素的信噪比。在当前病例中，在一项无意中使用60秒帧进行的研究中，漏诊了临床上记录的显著程度的反流，但随后使用10秒成像方案检测到了该反流。
