title: Digital imaging of the intracranial circulation using an aortic arch injection and carotid compression.
abstract: When selective catheterization of a common carotid artery is difficult, it is still possible to obtain adequate diagnostic films of the cerebral circulation in the lateral projection without marked superimposition of the intracranial vessels. This can be achieved angiographically by using digital recording after an arterial aortic arch injection and compressing the opposite carotid artery during imaging.
