NEUROLOGICAL ULTRASOUND

How is Ultrasound used for Neurology?

Ultrasound tests and procedures are vital tools that help physicians confirm or rule out the presence of neurological disorders and other medical conditions. The neurological department at ProVision provides a wide range of the latest technology and techinques to help identify patients who have had strokes or transient ischemic attacks (TIA), or who are at risk for stroke.

Blood flow to the brain may be examined using transcranial doppler (TCD). We are able to check the ophthalmic artery and measure cerebral vascular blood flow by looking at all of the major arteries and vessels of the Circle of Willis. The exam is non-invasive, painless, extremely safe and only takes fifteen minutes.

Physicians may order a carotid duplex ultrasound to scan the carotid arteries in the front of the neck. This can show if the blood vessels can become blocked or narrowed by atherosclerosis, which can raise a person's risk of stroke and TIAs.

ProVision also offers a Vestibular Autorotation Test (VAT) to evaluate both the high frequency horizontal and vertical vestibulo-ocular reflex (VOR). This computerized test of head and eye movement stabilizes fixation of the eyes during head rotation by causing the eyes to move in the opposite direction of the head motion.
