ASSESSMENT ON THE INTERCHANGEABILITY OF PERSONAL EFFECTIVE DOSE ALGORITHMS IN FLUOROSCOPY-GUIDED INTERVENTIONS USING BLAND-ALTMAN ANALYSIS

摘要

The effective doses received by radiology personnel over 230 FGIs in a year were assessed by using double dosimetry and five various algorithms (two OSL dosemeters that were worn by each staff). Additionally, Mest and linear correlation analyses were incorporated in this study to determine the significance of these algorithms, as well as the correlations between the estimated effective doses. Niklason and Japanese Regulation algorithms gave rise to significant correlation coefficients that ranged between 0.88 and 1.00. Meanwhile, the Shapiro-Wilk test revealed normal data distribution (p ＜ 0.01). The occupational doses received by the radiology personnel during the FGIs process appeared to be acceptable within the fixed limit. Evidently, the usage of different algorithms led to varied outcomes. Both Niklason and Boetticher algorithms exerted exceptional interchangeability in terms of effective dose estimations. In short, the strong correlation and good agreement between both algorithms could render them useful in FGIs.
