Upright MRI in spontaneous spinal cerebrospinal fluid leaks and intracranial hypotension.

Orthostatic headaches are the hallmark of spontaneous intracranial hypotension, but MRIs are traditionally obtained in the supine position. We investigated the utility of upright MRI of the brain in 6 patients with spontaneous intracranial hypotension. No discernable differences were noted between the supine and upright images.
