BACKGROUND AND AIMS: Increasing use of diagnostic radiography has led to concern about the malignant potential of ionizing radiation. We aimed to quantify the @entity7184 ( @entity7184 ) from diagnostic medical imaging in @entity1 with @entity29 ( @entity29 ) and to identify which @entity1 are at greatest risk for high amounts of image-related radiation exposure. @entity1 AND METHODS: A retrospective chart review of pediatric @entity29 @entity1 seen between January 1 and May 30, 2008 was conducted. The effective dose of radiation received from all of the radiology tests performed during the course of each @entity1 's treatment was estimated using typical effective doses and our institution's computed tomography dose index. A @entity7184 >= 50 @entity2073 was considered high. RESULTS: Complete records were available for 257 of 372 screened subjects. One hundred seventy-one had @entity30 ( @entity30 ) and 86 had @entity31 ( @entity31 ). The mean @entity7184 was 17.56    15.91 @entity2073 and was greater for @entity1 with @entity30 than for those with @entity31 (20.5    17.5 vs 11.7    9.9 @entity2073 , P < 0.0001). Fifteen @entity1 (5.8%) had a @entity7184 >= 50 @entity2073 , including 14 of 171 (8.2%) with @entity30 and 1 of 86 (1.2%) with @entity31 (P = 0.02). In @entity1 with @entity30 , factors associated with high @entity7184 per multivariate analysis were any @entity29 -related surgery (odds ratio 42, 95% confidence interval 8-223, P < 0.0001) and platelet count (odds ratio 16, 95% confidence interval 1.5-175, P = 0.02). CONCLUSIONS: Although all doses of ionizing radiation have some @entity5 -inducing potential, a small but important percentage of @entity1 with @entity29 are exposed to particularly high doses of ionizing radiation from diagnostic tests and procedures. Physicians caring for such @entity1 must seek to limit radiation exposure whenever possible to lessen the lifetime risk of @entity5 .
