- Abstract
Objective: To evaluate pediatric radiation exposure in procedures of Interventional radiology In two hospitals in the Bahia state, aiming at contributing to delineate the scenario at the state and national levels. The knowledge of exposure levels will allow an evaluation of the necessity of doses optimization, considering that peculiarities of radiology and pediatrics become even more significant In Interventional radiology procedures which involve exposure to higher radiation doses. Materials and Methods: A total of 32 procedures were evaluated in four rooms of the two main hospitals performing pediatric interventional radiology procedures in the Bahia state. Air kerma rate and kerma-area product were evaluated in 27 interventional cardiac and 5 Interventional brain procedures. Results: Maximum values for air kerma rate and kerma-area product and air kerma obtained in cardiac procedures were, respectively, 129.9 Gy.cm2 and 947.0 mGy; and, for brain procedures were 83.3 Gy.cm2 and 961.0 mGy. Conclusion: The present study results showed exposure values up to 14 times higher than those found In other foreign studies, and approximating those found for procedures In adults. Such results demonstrate excessive exposure to radiation, Indicating the need for constant procedures optimization and evaluation of exposure rates.
