Abstract:
Appropriate administered-activity verification and consistent explanations for patients and guardians are essential in pediatric nuclear medicine. We developed an offline HTML application integrating Japanese guideline-based activity calculation, reference effective-dose display, patient explanation-sheet generation, and facility-level master-data customization. Ten radiological technologists completed 10 simulated cases using conventional and application methods. Agreement within ± 3% of reference activities increased from 84.0% to 97.0% (p = 0.031), exact agreement increased from 49.0% to 97.0% (p = 0.0039), and mean task time decreased from 25.7 to 4.1 s (p = 0.0020). The tool supports verification rather than prescribing, and its dose display excludes CT exposure from hybrid examinations. After local master-data validation, it can support consistent calculation under its implemented rules.
