Pharyngeal videofluoroscopy (VTF) is a well-recognized technique for investigating and assessing swallowing disorders. There is, however, a paucity of data available regarding the radiation dose to patients during such procedures, but there is general concern that fluorographic imaging modalities are associated with significant radiation exposure. We have recorded the dose received by 23 patients undergoing VTF in our department using a Dose-Area Product (DAP) Meter and have used the data to calculate the effective dose to the patients. The mean effective dose is 0.4 mSv (range 0.027-1.1) which compares favorably with the effective doses associated with other common radiological procedures. We therefore conclude that the radiation detriment associated with pharyngeal VTF is well within acceptable levels.
咽部视频荧光透视检查（VTF）是一种公认的用于研究和评估吞咽障碍的技术。然而，关于此类检查过程中患者所接受的辐射剂量，现有数据较少，但人们普遍担心荧光成像方式会带来显著的辐射暴露。我们使用剂量面积积（DAP）仪记录了在我们科室接受VTF检查的23例患者所接受的剂量，并利用这些数据计算了患者的有效剂量。平均有效剂量为0.4毫希沃特（范围为0.027 - 1.1），与其他常见放射学检查相关的有效剂量相比具有优势。因此，我们得出结论，咽部VTF相关的辐射危害完全在可接受水平之内。
