Aortic and Hepatic Contrast Enhancement with Abdominal 64-MDCT in Pediatric Patients: Effect of Body Weight and Iodine Dose

Abstract

In our study, using abdominal 64-MDCT in pediatric patients, we found that approximately 1.5 mL/kg, or 0.525 g I/kg, yields 116 HU of hepatic attenuation or 50-55 HU of hepatic enhancement.
