44 years old. prolactin at 26.3 do i need an mri?

Is prob indicated: An MRI of the head (specifically pituitary gland) with and without contrast is probably in your future. But, you need a complete history and physical, appropriate labs (maybe already done) and possibly other tests. High prolactin may be caused by a prolactinoma, a tumor of of the pituitary gland, which regulates many hormone feedback loops and is located at base of the brain behind nasal bridge.
