Patient Dose During Videofluoroscopy Swallowing Studies in a Hong Kong Public Hospital

The mean fluoroscopic time is 4.23 ± 2.56 min. The P value of 0.0034 was obtained using the Kruskal–Wallis test to compare the DAP from various groups of indicating pathologies. It suggests that there are significant differences in dosage between CVA and NPC patients and the entire population. We conclude that the dose of radiation received by a patient undergoing a VFSS examination in our center was comparable to the international standard and that of other similar studies. We can also conclude that there is a significant difference in dosage between NPC and CVA patients and the overall population suggesting that the indicating pathologies for a VFSS have certain effects on the resulting irradiating dose delivered but more studies have to be done to explain such differences.
