If i had a pituitary adonema would a standard brain mri with and without contrast show it?

Yes.: Dynamic contrast MRI has been proven to be the best imaging tool in the evaluation of pituitary adenomas.

Maybe: Pituitary adenomas MRIs are very specific protocols. If you have a 'macroadenoma' which is larger than the normal gland, a routine MRI protocol would still likely show this. However, 'micoadenomas' can be only a few millimeters in size and a routine brain protocol MRI could miss it based on scan slice thickness or it may not stand out within the normal tissue.

Depends on size: The limit of resolution for a typical MRI magnet is about 1 to 2 mm, so microadenomas (small adenomas) in the pituitary less than this size will probably not be seen. Contrast can help, but not all adenomas take up contrast. All tests, even the "mighty" MRI, has its limitations. Microadenomas are usually found by testing diff hormones - talk to an endocrinologist.

Hi! If you do an MRI of the pituitary can you also see if there would be something wrong in the other parts of the brain?
