title: Noninvasive testing of the carotid system.
abstract: Noninvasive diagnostic techniques have a high degree of accuracy in identifying hemodynamically significant narrowing of the extracranial carotid artery. Ocular pneumoplethysmography, periorbital Doppler ultrasonography and cerebrovascular thermography focus on the ophthalmic artery and its branches as well as terminal branches of the external carotid artery. Carotid phonoangiography and ultrasonic Doppler arteriography focus directly on the cervical carotid complex.
