Enhancement of parallel MR image acquisition by rotation of the plane of section.

abstract：:An angiographic system capable of simultaneous biplane stereoscopic magnification cerebral angiography was evaluated. Stereoscopic imaging improved the morphologic depiction of aneurysms and of arteriovenous malformations. In a series of 357 patients, procedure time was reduced because the initial biplane stereoscopic...
