The Carotid Artery is the main supply of blood to the brain, which is at risk of blockages that may lead to Carotid Stenosis among other conditions.
The Ultrasound Scanner imaging modality comes into the picture to detect these blockages. Using a High Accuracy Ultrasound Probe, the physician can decide on the appropriate intervention needed.
For example, in order to conduct an Endarterectomy and after a Carotid Endarterectomy is performed, the Neurosurgeon may continue to use Carotid Ultrasound using Doppler Linear probe to ensure that the Endarterectomy worked and the blockage is gone.
Which ultrasound scanner do doctor use for neuro-monitoring?
Carotid Ultrasound, Images of the Brachial Artery and common Carotid are captured using a Linear Array Ultrasound Scanner Of a 9MHz Frequency like the SIFULTRAS-5.34.
On the other hand, the Internal Carotid images are captured at 13MHz using the SIFULTRAS-3.53.
Ultrasound helps the doctor to determine the risk of Cerebral Embolization: By using Ultrasonography, the medical professional can identify plaques in the carotid arteries and detect passage to the brain, very tiny bits of blood clots or plaque material. This helps understand the risk for, or cause of, stroke, allowing treatment to prevent a new stroke.
Ultrasound is also used to evaluate patients’ cerebrovascular reserve—typically during a stress test of the brain arteries —to can make sure there is normal capacity to increase blood flow to the brain when under stress. If blood flow can't increase during a stress test, your brain is at risk for stroke.
Ultrasound neuro-monitoring is done by a radiologist or neurologist.
