Pituitary MRI with Contrast

A focused contrast-enhanced MRI of the pituitary gland and sella turcica region, used to detect microadenomas, macroadenomas, and other sellar or parasellar pathology. Requires a physician referral.

The pituitary gland sits within the sella turcica at the base of the brain and controls a wide range of hormonal functions. Pituitary MRI with dynamic contrast enhancement is the standard imaging modality for evaluating suspected pituitary adenomas, which are among the most common intracranial tumours. The examination uses thin-slice coronal and sagittal sequences with rapid contrast timing to capture the differential enhancement between normal pituitary tissue and adenomas. Microadenomas (under 10mm) enhance more slowly than surrounding tissue, creating a detectable contrast on dynamic sequences. Macroadenomas (over 10mm) are typically visible on standard sequences but benefit from contrast to assess cavernous sinus invasion and optic chiasm compression. This scan is particularly relevant for patients with unexplained hormonal abnormalities including elevated prolactin, Cushing's syndrome, acromegaly, or panhypopituitarism. Available at both locations with physician referral required.
