title: Rapid high dose (RHD) contrast computed tomography of perisellar vessels.
abstract: The diagnostic accuracy of CT scanning in the sellar area can be improved by using a rapid high dose (RHD) contrast technique which visualizes the supraclinoid carotid arteries, cavernous sinus and vascular plexus of the infundibulum. The RHD technique is briefly described and the pertinent anatomy discussed and illustrated.
