Pretty much every MRI ordered has DWI. They order MRI with and without contrast pretty much routinely at most places. It is what they use clinically that counts though. At Mayo they do not use the DWI in the urology procedures diagnostically. They are pretty much just contrast for clinical purposes. But because they take MRI with and without, sending to Dr Scionti he can look at the without contrast images or DWI images and say what he sees. Believe me they order MRI everyday almost everywhere with and without, but they use what they use clinically and the rest is just like filler at places. For brain tumors and so on the DWI is real key. But anyway... too much info probably.

@dbee Was your MRI on the old 1.5 machine or 3.0 machine ?
