If it is for low testosterone they are looking for a pituitary adenoma or empty sella syndrome. An adeonoma is a very small usually benign tumor on the pituitary that can interfere with it working properly by putting pressure on it. Empty sella is more complicated and has to do with the cavity the pituitary is in filling with fluid I believe. It is very rare. It is not very scary but you can arrange to do it in one of the new open MRI machines if you are more comfortable. I just keep my eyes closed and try to take a nap during the procedure.
Several of my docs have indicated that even the new open MRI machines do not have the resolution of the closed machines. They all, however, have offered a script for valium, which makes it bearable for me. As hayfarmer indicated, under no circumstances, open your eyes in there. Also, ask them to keep you up to date on the status. When you hear things like "next phase, 90 seconds, 4 more to go" it makes it easier.
As to why? Why not ask the doctor that ordered it? we can only guess here.
It is scary for me , I have had 4 MRI's on my back so far and everyone gets harder for me , even the valuim doesn't help much . I thought maybe the bloodwork showed somthing cancerous or somthing..Thanks for your help. Hayfarmer you should devote your time to be a Dr. You seem to know so much .
Thanks Shawley. It is strange you have had 4 MRI's. Maybe they are seeing some artifact on the MRI they can not identify. I would ask your doc why you need another one and what he is looking for. I have had 2. On reason to do more than one is the adenomas are very small and hard to find. If you wait a year or two and retest you may find it has grown and you can see it now. You can also then compare one MRI to the other for changes. I'm not an expert on MRI machines but some do have better resolution than others and you need the best type for an adenoma.
While I don't find it scary I also don't like it. My technique is to just keep my eyes closed and relax and think about something else as much as possible.
