Abstract：
UNASSIGNED: The salivagram was first described to detect possible lung aspiration in infants or young children. Its original protocol required dynamic imaging for 60 minutes, which has high sensitivity. The purpose of this retrospective investigation was to determine whether a shortened period of image acquisition can be adopted without significantly reducing the sensitivity of the test in detecting aspiration.
UNASSIGNED: The current salivagram protocol in our hospital requires 60 minutes of dynamic imaging. The images of a total of 398 patients (ages 1 month to 9 years old) with positive salivagrams were analyzed. The entire 60-minute dynamic images were divided into 6 periods, 10 minutes/period. The time of the onset of abnormal activity in the bronchi, which was evidence of aspiration in each patient, was recorded and assigned to the corresponding period.
UNASSIGNED: Among all 398 patients with evidence of aspiration, tracheobronchial tree activity could be seen in the first 10 minutes of the dynamic imaging in 184 of them (46.2%, 184/398). The onset of the bronchial activity was seen between 10 and 20 minutes in 177 patients (44.5%, 177/398). A total of 35 patients (8.8%, 35/398) had the onset of abnormal tracheobronchial tree activity in the 3rd period between 20 and 30 minutes. During the 4th period between 30 and 40 minutes, the onset of the aspiration occurred in only 2 patients (0.5%, 2/398). All patients had the onset of aspiration in the first 40 minutes of the dynamic imaging.
UNASSIGNED: The originally described 60-minute dynamic imaging protocol of the salivagram can be safely shortened to 40 or even 30 minutes without a significantly decreased chance of detecting aspiration. Prolonged imaging is unnecessary.

摘要：
■首先描述了salivagram以检测婴儿或幼儿可能的肺吸入。它的原始协议需要动态成像60分钟，具有高灵敏度。这项回顾性调查的目的是确定是否可以采用缩短的图像采集时间，而不会显着降低检测误吸的测试灵敏度。
■我们医院当前的salivagram方案需要进行60分钟的动态成像。分析了398例唾液分泌阳性患者（1个月至9岁）的图像。整个60分钟的动态图像分为6个周期，10分钟/周期支气管异常活动开始的时间，这是每个病人误吸的证据，被记录并分配到相应的时期。
■在所有398例有误吸证据的患者中，在184例动态成像的前10分钟可以看到气管支气管树的活动（46.2％，184/398）。在177例患者中，支气管活动的发作在10到20分钟之间（44.5％，177/398)。共有35名患者(8.8%,35/398）在第3个时期在20到30分钟之间出现了异常的气管支气管树活动。在第4个30到40分钟之间，仅2例患者发生误吸（0.5％，2/398）。所有患者在动态成像的前40分钟内都发生了误吸。
■最初描述的唾液造影60分钟动态成像方案可以安全地缩短到40甚至30分钟，而不会显着降低检测到误吸的机会。长时间成像是不必要的。
