Ultrasound & Neuro-Doppler

General information

Ultrasound is a non-invasive imaging technique that sends high-frequency sound waves into the body to produce images of internal organs and soft tissue.

The ultrasound procedure involves passing a device called a transducer over the skin of the area to be examined.

 

Based on sonar technology used in submarines the transducer acts like a speaker producing the high frequency sound waves, and as a microphone receiving the echoes/ sound waves that bounce back from the internal structures.

 

These returning echoes are then processed to produce ultrasound images.


Doppler ultrasound is an enhanced ultrasound that studies blood flow. The Doppler effect assesses whether blood is moving away or towards the transducer and its relative velocity.

Neuro Doppler examinations provide a diagnostic tool to investigate blood flow in the head and neck.
