Advances in CT technology and application to pediatric imaging.
ABSTRACT The use of imaging in both hospital and non-hospital settings has expanded to more than 70 million CT procedures in the United States per year, with nearly 10% of procedures performed on children. The availability of multiple-row detector CT (MDCT) systems has played a large part in the wider usage of CT. This rapid increase in CT utilization combined with an increasing concern with regard to radiation exposure and associated risk demands the need for optimization of MDCT protocols. This manuscript will briefly discuss how technology has changed in regard to MDCT protocols, helping to reduce radiation dose in CT, especially in pediatric imaging.

- "Pediatric radiation exposure from medical imaging, and its implications for long-term development of cancer, remains a major international health concern . Most estimates have been extrapolated from atomic bomb survivors in Hiroshima and Nagasaki, a cohort strikingly dissimilar from today's standard pediatric patients undergoing CT scans . In our series, several steps were undertaken to ensure low levels of radiation, including weight-based radiation dosing and retroverted CT slices. "
ABSTRACT: Diagnosis of lower gastrointestinal bleeding (LGIB) represents a significant diagnostic and therapeutic challenge for any physician. While CT enterography (CTE) has been applied in adults with occult LGIB, its use in children has been limited to evaluation of Crohn's disease. We reviewed 6 patients ages 4-15 who underwent CTE for LGIB at a tertiary pediatric institution. In sum, CTE appears to be a valuable tool for localizing the source of LGIB prior to surgical or endoscopic intervention. However, rapid lesion identification must be weighed against the increased radiation exposure and patient discomfort due to bowel distention associated with this diagnostic technique.Journal of Pediatric Surgery 03/2013; 48(3):681-684.
