We routinely do CT power injection. The question has arisen re MRI power
injector. Our MRI group uses an injector made by MEDRAD. I'm told that it can
reach 350 psi but it is set much lower. The MRI manager states that "MEDRAD
power injectors are internally programmed to deliver 350 psi and that parameter
cannot be changed even though we routinely inject at much lower rates. Psi can
vary depending on a variety of factors such as temp, viscosity,length of
catheter,etc" If you set your power injector to deliver a specific psi would it
actually be capable of going higher just because it has the potential to go to
350 psi? This doesn't make sense to me. Someone out ther able to shed some
light on this? We currently are using power piccs that can handle 300psi
