MRI is the optimum method of imaging the pituitary of patients with suspected pituitary disease though CT is an acceptable alternative. The advantages of MRI are: direct multiplanar scanning, lack of ionizing radiation, and good anatomical tissue discrimination. Imaging the pituitary gland and hypothalamus is best performed in the sagittal and coronal planes because they show the relationships between gland and adjacent structures. Scanning in the axial plane alone is a poor technique for demonstrating vertical relationships between structures lying between the floor of the third ventricle and sella turcica. Computer-generated three-dimensional (3D) reconstructions of axially acquired data (by MR or CT) and can be viewed in any plane can compensate but usually direct scanning gives better resolution images.
