RESUMO
In the last 15 years there has been a relative explosion in the number of magnetic resonance imaging (MRI) techniques and developments related to cerebral perfusion. Given the variety of perfusion methods available, it is often difficult to decide which technique would be best for a particular clinical question or patient. In this review article we discuss the more common techniques, review how they are performed, and summarize the optimal technique or techniques for a variety of clinical situations.

We present a 38-year-old woman with bilateral serous retinal detachments and bilateral panuveitis on fundoscopic exam. CT of the orbits and MRI scans revealed bilateral ocular choroidal thickening and bilateral retinal detachments; however, no other CNS or meningeal lesion was detected. This patient met the clinical criteria for Vogt-Koyanagi-Harada (VKH) Syndrome. Review of VKH syndrome as well as the radiographic findings will be discussed.
