Overview
MRI is done if the CT scan is suspicious for pituitary apoplexy. MRI is more sensitive than CT scan. MRI scan is more accurate in distinguishing the soft tissues of the pituitary from the surrounding bony structures. It is also superior to CT scan for detecting ischemia and infarction in brain tissue.
MRI
MRI is done if the CT scan is suspicious for pituitary apoplexy. MRI is more sensitive than CT scan. MRI scan is more accurate in distinguishing the soft tissues of the pituitary from the surrounding bony structures. It is also superior to CT scan for detecting ischemia and infarction in brain tissue. MRI may show:
- Enlargement of pituitary gland.
- Compression of optic chiasm and surrounding structures.[1]
- Hemorrhage evident by hyperintense center in pituitary gland.
- Necrosis evident by hypointense center in pituitary gland.
MRI can also be done to determine response to therapy.
