Conclusion and recommendations
A total of 99 patients were analyzed in a 12 years period. We obtain a mean age of 6.19 years, with a mean follow-up time of 4.78 years (range 0.08-12.14).
We calculate a mean total of 49.43 studies per patient. The 43.4% of the global cumulative EDR was contributed by CT-scans. The distribution of cumulative ERD per type of procedure is shown in Fig. 2 .
Using our ERD reference table, the cumulative ERD was of 74.64 mSv per patient (range 0.02-711.59). 60% of the patients cumulative ERD is avobe the 30 mSv lower limit (green line, Fig. 3 ). No evidence of direct detrimental radiation effect was found in the EHR.
Although it is not possible to establish the consequences, this finding implies an alarm signal about potential morbidity added to this group of patients.
The quantification of the cumulative effective dose exceeds the lower recommended standards of 30 mSv. With these results, we start to develop strategies to improve the justification and optimization of requested studies, specially on CT-scans, with a multidisciplinary approach between pediatrics, surgeons, and radiologists.
