Comments: Bolus Tracking is performed off the abdominal aorta using a 200 HU trigger setting.  For all CT Enterography patients the following protocol is used regarding oral contrast administration:

-        1st  Dose 450 ml of Volumen  ( Drink slowly within the first 10 minutes)

-        2nd Dose 450 ml of Volumen  (10 minutes after 1st dose of Volumen)

-        3rd Dose 450 ml of Volumen   (10 minutes after 2nd dose of Volumen)
