Background And Purpose: In the anterior circulation, the hyperdense middle cerebral artery (MCA) sign is a well-established marker for early ischemia.

The purpose of this study was to define the hyperdense posterior cerebral artery (PCA) sign and determine its incidence, diagnostic value, and reliability as a marker for ischemia in the territory of the PCA.
