Why Ultrasound Is One of the Safest Imaging Tools Available

June 18, 2025

An ultrasound scan is used to see images of the inside of your body, such as muscles, organs, or a baby in your womb.

It uses high-frequency sound waves to create real-time pictures or video of internal organs or other soft tissues, such as blood vessels.

Ultrasound is based on non-ionising radiation, unlike some other medical imaging tests, such as X-rays and CT scans, so does not have the same risks.

Ultrasounds that are performed externally (over your skin) are generally not painful. You won’t feel the sound waves that ultrasound uses.

Research to date has largely shown ultrasound technology to be safe with no harmful side effects or known risks.

Images created from an ultrasound scan can help to guide diagnosis and treatment for many diseases and conditions.

Diagnostic Ultrasounds

Diagnostic ultrasounds are used at firstScanHealth to view internal parts of the body to see if something is wrong or not working properly.

These scans can help us to understand what the cause of any symptoms you might be experiencing could be.

At firstScanHealth, all our diagnostic scans are conducted externally.

Our sonographers will place the transducer (probe) on your skin and move it around to create a real-time image of your body and its organs.

When is an ultrasound scan recommended?

Typically, you might be recommended a diagnostic ultrasound when your healthcare provider needs to visualise your internal organs or tissues to diagnose a medical condition, monitor a condition, or guide a procedure.
