===Weight adjustment===
The needed dose is proportional to the ''lean body weight'' of the patient. For contrast CT, this is optimally calculated by the Boer formula, using height and weight of the patient.<ref name="CarusoDe Santis2018">{{cite journal|last1=Caruso|first1=Damiano|last2=De Santis|first2=Domenico|last3=Rivosecchi|first3=Flaminia|last4=Zerunian|first4=Marta|last5=Panvini|first5=Nicola|last6=Montesano|first6=Marta|last7=Biondi|first7=Tommaso|last8=Bellini|first8=Davide|last9=Rengo|first9=Marco|last10=Laghi|first10=Andrea|title=Lean Body Weight-Tailored Iodinated Contrast Injection in Obese Patient: Boer versus James Formula|journal=BioMed Research International|volume=2018|year=2018|pages=1–6|issn=2314-6133|doi=10.1155/2018/8521893}}</ref> Taking this formula, the needed volume of IV contrast from the unadjusted volume given in the table above becomes:
*For men: Weight-adjusted volume = Unadjusted volume x ((0.00581 × W) + (0.00381 × H) − 0.274)
*For women: Weight-adjusted volume = Unadjusted volume x ((0.0036 × W) + (0.00676 × H) − 0.69)
, where W is body weight in kilograms and H is body height in centimeters.
