The radionuclide "salivagram" was introduced to document the aspiration of oral secretions in patients who are at risk. Approximately one-third of patients studied had positive tests. A positive study does not necessarily imply that patients are at risk for aspiration after gastroesophageal reflux. However, sequential images of the lung fields after the oral radioactivity has cleared may be a sensitive technique for detecting aspiration in infants and children following reflux.
放射性核素“唾液造影”被用于记录有风险患者口腔分泌物的误吸情况。约三分之一接受研究的患者检测呈阳性。阳性研究结果并不一定意味着患者在胃食管反流后有误吸风险。然而，口腔放射性物质清除后肺部区域的连续图像可能是检测婴儿和儿童反流后误吸的一种敏感技术。
