Abstract

The growing use of CT as a diagnostic imaging tool has led to increased concern over radiation dose, particularly in pediatric patients. The ALARA concept has been popularized in dose reduction. ALARA supports the use of low-dose, pediatric-specific protocols. Strict adherence to low-dose protocols can be challenging, particularly in a high-volume radiology department that scans both pediatric and adult patients. The aim of this study was to determine whether the relocation of pediatric radiologic services from a combined high-volume pediatric and adult hospital to a children's hospital improves compliance with adjusted lower CT exposure parameters and thus the estimated effective dose of radiation delivered to pediatric patients. A retrospective review of abdominal and pelvic CT console dose and exposure parameter data on 495 patients from a combined pediatric and adult radiology department and subsequently 244 patients from a dedicated pediatric radiology department was performed. The console dose-length product was converted to estimated effective dose. Patients were divided into 1 of 8 weight categories for analysis. A statistically significant decrease in the estimated effective dose for abdominal and pelvic CT studies was...Continue Reading
