*2.9 ml * 31 = 90 ml
With the local iodine concentration being 350 mg/ml, the weight-unadjusted volume needed for the abdominal CT is estimated to be 60 ml. The patient weights 120 kg and is 176 cm tall. The weight adjusted volume is thus:
*60ml × ((0.00723 × 120) + (0.00474 × 176) − 0.341) = 82 ml
