ENT Ultrasound

Phone number forRadiology Department

ENT Ultrasound is a procedure that uses high-frequency sound waves to view internal organs and produce images of the human body. During the ultrasound exam, a device called a transducer is used to view the target area and produce pictures for the study. The transducer emits sound and detects the returning echoes when it is placed on or over the body part being studied.

Ultrasound uses no ionizing radiation, making it a safe exam, even for pregnant women and children. An ultrasound guided biopsy is an exam that uses a small needle to obtain tissue samples of the area in question performed with ultrasound guidance.
