We have converted from Magnevist (gadopentetate dimeglumine):
Dose 0.1 mmol/kg, concentration 0.5 mmol/ml, so you give about one ml/10 lb up to 20ml
for example:
150 # pt would get 15 ml
220 # pt would get 20 ml
(roughly 1mL/pound)

to a newer agent, Gadovist (gadobutrol) that is twice as concentrated as the other products:
Dose 0.1 mmol/kg concentration 1mmol/ml so you give half the volume as the other agents. (about 0.5ML/10 lb)

for example:
150 # pt would get 7.5 ml
220 # pt would get 11 ml
(roughly 0.5mL/pound)
Pt came to the private office and noted they weighed 10 stones? now what?
A: google tells us that 1 stone is 14 pounds so the pt weighs 140 pounds, give 7mL Gadovist.
We have a blood pool agent available as well, Ablavar
