I'm having an MRI tomorrow for a suspected pituitary gland problem. I had an MRI about 5 years ago for a dizziness / balance problem. Question: if there was a problem with the Pituitary gland back in 2005 would the brain MRI have picked it up or does the Endocrinologist order a set of special MRI scans just for the Pituitary Gland?
That's a good question. I've had numerous brain MRIs and my understanding is that the radiologist looks for any abnormalities throughout the whole brain, including the pituitary. I would think that if you had an adenoma of the pituitary back in 2005 it would have showed up then. But that was nearly 5 years ago and things can change in that period of time.
I was also told by my neurologist that there are better and worse MRIs. The open MRIs are far less sensitive than the closed ones. There is also a contrast dye (gadolinium) that can be injected to provide a much more detailed picture. But you should not use gadolinium if you have any kidney disease.
I had an MRI last year for my pituitary gland. Nothing showed up, but my dr. said I still probably had a sluggish pituitary gland since my hormones were always low. So just because nothing shows up, doesn't mean there's not a problem.
