Ultrasound

Ultrasound

Ultrasound, also known as sonography, is a non-invasive diagnostic imaging technique that uses high-frequency sound waves to create real-time images of the inside of the body. It is commonly used to examine internal organs, monitor fetal development during pregnancy, detect abnormalities and guide certain medical procedures. Unlike X-rays, ultrasound does not use ionizing radiation, making it a safe and preferred method for various medical evaluations. The procedure is quick, painless and typically performed using a handheld device called a transducer, which is moved over the skin after applying a special gel to ensure clear image transmission.


1. How does Ultrasound work?

A handheld device called a transducer sends sound waves into the body and captures the echoes as they bounce back, which are then converted into visual images on a screen.

Yes, ultrasound is completely safe. It does not use any ionizing radiation and is commonly used even during the pregnancy to monitor fetal health. It generally has no side effects.

Preparation for an ultrasound depends on the type you’re having. Example, you might need to skip food before an abdominal scan or drink water to fill the bladder for a pelvic scan.
