Why would a doctor order an MRI of the pituitary gland?

A doctor performs an MRI of the head to determine if a pituitary tumor is present. This scan can also help doctors determine whether a pituitary tumor is growing into nearby tissue.

Does an MRI of the brain show the pituitary gland?

What does a brain MRI without contrast show?

Even without the intravenous contrast, MRI can detect pathology in most organs and in some cases the pathology is made less visible on a contrast MRI than a non-contrast scan. For example, non-contrast scans provide greater images of blood vessel activity to detect aneurysms and blocked blood vessels.

What is pituitary protocol?

MRI protocol for pituitary gland is a group of MRI sequences put together to improve sensitivity and specificity for the assessment of lesions of the pituitary gland (e.g. pituitary adenoma) and other sellar and suprasellar abnormalities (check the article on pituitary region masses for some examples).
