Optimization of high-concentration (400 mgI/mL) contrast media volume for abdominal computed tomography: a comparison between fixed-dose and total body weight-based protocols
In abdominal multiphasic contrast-enhanced CT, the TBW-based protocol of 450 mgI/kg at 100 kVp is recommended for assessing vasculature, and the TBW-based protocol of 500 mgI/kg at 120 kVp is recommended for parenchymal and tumor visualization.
