降低透视脉冲率是一种用于减少改进的X线吞咽研究(MBSS)的辐射暴露的方法，它减少了可用于判断吞咽损伤的图像数量。有必要了解脉率降低对吞咽损害判断的影响，以及相应的治疗建议。这项初步研究探索了两种脉率：每秒30次和模拟15次(PPS)之间的标准化MBSS测量[改良的吞钡损害轮廓(MBSImP(TM)A(C))和穿透吸引量表(PAS)评分]的差异。两位可靠的言语语言病理学家(SLP)对所有五个MBSS进行了评分。五个SLP根据这些分数报告了治疗建议。在所有五个MBSS中，吞咽障碍的判断在30个PPS和模拟15个PPS之间发现差异。这些差异表现在咽咽起始、舌骨前移、会厌运动、咽收缩、咽-食管段张开和舌根后缩等6个生理吞咽成分上。在所有五个MBSS中，在30和模拟15个PPS之间发现了治疗建议的差异。这些发现表明，当脉率从30次/秒降至15次/秒以将辐射暴露降至最低时，吞咽损害的判断和治疗建议都存在差异。
Reducing fluoroscopic pulse rate, a method used to reduce radiation exposure from modified barium swallow studies (MBSSs), decreases the number of images available from which to judge swallowing impairment. It is necessary to understand the impact of pulse rate reduction on judgments of swallowing impairment and, consequentially, treatment recommendations. This preliminary study explored differences in standardized MBSS measurements [Modified Barium Swallow Impairment Profile (MBSImP (TM) A (c)) and Penetration Aspiration Scale (PAS) Scores] between two pulse rates: 30 and simulated 15 pulses per second (pps). Two reliable speech-language pathologists (SLPs) scored all five MBSSs. Five SLPs reported treatment recommendations based on those scores. Differences in judgments of swallowing impairment were found between 30 and simulated 15 pps in all five MBSSs. These differences were in six physiological swallowing components: initiation of pharyngeal swallow, anterior hyoid excursion, epiglottic movement, pharyngeal contraction, pharyngeal-esophageal segment opening, and tongue base retraction. Differences in treatment recommendations were found between 30 and simulated 15 pps in all five MBSSs. These findings suggest that there are differences in both judgment of swallowing impairment and treatment recommendations when pulse rates are reduced from 30 to 15 pps to minimize radiation exposure.
