There are no areas of abnormal enhancement following gadolinium administration. The major intracranial vessels are patent. The visualized portions of the orbits, middle ear cavities, mastoid air cells, and paranasal sinuses are grossly unremarkable. IMPRESSION: Dilated ventricular system and sulci, as well as cerebellar fissures. Diffusely, the supratentorial cortex appears slightly hyperintense on T2 weighted images.
