Pediatric Ophthalmic Computed Tomographic canning and Aociated Cancer Rik

Purpoe To review pediatric neuroimaging tudie of the head and orbit and the radiation-induced cancer rik aociated with computed tomography in light of recent attention to pediatric radioimaging by the U Food and Drug Adminitration, the National Cancer Intitute, pediatrician, and radiologit. Deign Perpective. Method Literature review. etting: Intitutional. patient population: Pediatric ophthalmic patient requiring neuroimaging tudie. intervention/procedure: Review of the current literature. main outcome meaure: After review of the current literature and dicuion of the related iue, recommendation are made for pediatric neuroimaging tudie of the head and orbit. Reult Computed tomography (CT) of the head and orbit may be performed in children with the appropriate indication a long a the radiation expoure i minimized. Concluion Information obtained from CT can of the head and orbit may determine or affect management in the pediatric ophthalmic population. Becaue of the concern of cancer induced by radiation expoure in children, neuroimaging modalitie without radiation expoure, uch a magnetic reonance imaging or ultraound, may be conidered. However, when CT i indicated, it i reaonable and acceptable to perform CT of the head and orbit while minimizing the radiation expoure, thereby adhering to the “ALARA” (a low a reaonably achievable) policy recommended by the U Food and Drug Adminitration. Further tudie of the actual radiation doe delivered during pediatric CT of the head and orbit and the true incidence of radiation-induced cancer after can are warranted.
