Overview

MRI is done if the CT scan is suspicious for pituitary apoplexy. MRI is more sensitive than CT scan. MRI is more accurate in distinguishing the soft tissues of the pituitary from the surrounding bony structures. MRI is also superior to CT scan for detecting ischemia and infarction in brain tissue.
