Hiya-
The MRI process is well described here:
http://www.medhelp.org/medical-information/show/170/MRI
A radiologist who specializes in reading MRIS of the pituitary gland will look at all of the films and then summarize his/her findings into a report. This report will get sent to the doctor who referred you for the MRI.
Regardless of the resuts, the referring doctor will make an appointment to see you and discuss the report. They usually don't want the patient to get hold of the report before they can see you. Mostly because the medical terminology is intense and they don't want you running around freaking out before they have a chance to review thiings with you first, Sometimes thay can read mris themselves (mine do) and they will pull up the films on the computer that is in the exam rooms and show you what is going on.
One important thing ask the MRI tech for a copy of your MRI on a CD.
