Is it possible for a pituitary tumor to show up on an MRI done in the open style scanners?
Q:
A: Well maybe, but if your Dr. is looking for a pituitary tumor it really should be done as a "pituitary MRI" with and without contrast, not just a brain MRI. These are typically not done in open style scanners that I know of, but I could be wrong.
How often do brain tumors show up on MRI scans?
Q: ..or any other serious brain disorder. I'm not sure if MRI scans are a pretty routine thing now, but my Dad has just been for one. I'm wondering how worried I should be.I'm guessing if the doctor sent him, it's most likely going to be pretty serious?
A: No, you can't assume it's serious yet. An MRI is very good at showing all kinds of brain conditions - and at ruling them out. Doctors send patients for them because they're such a great diagnostic tool. It's not like they wait until they think it's serious to have someone get an MRI.Of course, if your dad does have something wrong, an MRI is going to show it more clearly and at an earlier stage. But it could be something other than a tumor, too. For example, MRI scans show old head injuries, blood vessel irregularities, epilepsy and so on.Sit tight and don't assume the worst. And good luck to both you and your dad.
How does a tumor look on an MRI?
Q: I recently had an MRI done (brain) and there is a mass in the middle of my left side of my brain that doesn't seem like it should be there. It was with contrast, some images it shows as darker than the areas around it, and some as brighter. Is this a tumor? If not, what else could it be? I am waiting for my neurologist to call me back, but it's so hard to not worry endlessly about it. Any info on how a tumor looks, and what else could appear like one, would be greatly appreciated.
A: I have brain cancer so I'm pretty familiar with what you are probably looking at. My tumor was noticeable without contrast and was white. With contrast my tumor was BRIGHT white. Some parts of the brain look whitish/greyish on films but that doesn't necessarily mean you have a tumor... it could be the scan or naturally supposed to be that way. Stop worrying so much is my best advice. A dead give away for me was the amount of time I was in there. My scan was supposed to take 20 minutes (searching for what we thought would be a pinched nerve) and I was in the MRI machine for nearly 2 hours. Don't fret until you hear the results from your doctor =) Please keep us updated!!
