BMI-based radiation dose reduction in CT colonography.

Rationale And Objectives: There is potential for x-ray dose reduction in computed tomography colonography (CTC) relative to body mass index (BMI). We evaluated the association between BMI and three-dimensional (3D) CTC image quality to assess the potential utility of BMI as the basis for radiation dose reduction in CTC.

Materials And Methods: Ninety-six consecutive patients underwent CTC and were randomized for scanning at 15 or 30 mAs.

Ectopic pancreas presenting with pancreatitis and a mesenteric mass.

Ectopic pancreas is defined by the presence of abnormally situated pancreatic tissue that lacks contact with normal pancreas and possesses its own duct system and vascular supply. Ectopic pancreas in the gastrointestinal tract is not uncommon. Moreover, there are several reported cases of adult ectopic pancreatitis in the literature, but to date, only two cases of pediatric ectopic pancreatitis have been reported.
