Rotational cerebral angiography: procedure and value.
Rotational cerebral angiography provides continuously changing projections and correspondingly excellent visualization of aneurysms or other vascular malformations requiring special or oblique views. Rotation angiography as part of the routine angiography gives a three-dimensional impression with one injection and series of films. Although additional subtraction technique is not possible and the injection time has to be prolonged, the technique is nevertheless advantageous compared with magnification angiography and angiotomography in the preoperative evaluation of cerebral vascular malformations.
