Ultrasound

Ultrasound

Ultrasound involves the use of sound waves whose echoes are used to produce images. It is not associated with any radiation exposure and so it is completely safe in pregnancy.

With ultrasound we can be able to image the following systems:

Ultrasound technology is excellent at visualizing soft tissues, such as organs and muscles.
