What is a soft tissue ultrasound

A soft tissue ultrasound examines lumps, swellings and other superficial structures under the skin. It can help identify cysts, lipomas (fatty lumps), lymph nodes, haematomas (bruised/blood-filled areas), and other soft tissue findings.

Why might it be requested

This scan may be requested to assess a lump or swelling noticed by you or your clinician. The scan helps characterise the nature of the lump - whether it is fluid-filled, solid or mixed.

How should I prepare

No special preparation is usually required for a soft tissue ultrasound. Follow the instructions given by your clinic.

What should I wear

Wear clothing that allows easy access to the area being examined. For a lump on the arm, a short-sleeved top is helpful. For a lump near the groin, loose trousers may be easier.

What happens during the scan

Gel is applied to the skin over the lump or swelling and a probe is moved gently over the area. The sonographer will assess the size, shape and characteristics of the lump. The scan is generally very quick and well tolerated.

Will it hurt

The scan is generally painless. Mild pressure over the lump is applied.

How long does it take

Approximately 15 to 30 minutes, depending on the location and nature of the lump.

When will I get results

Results are sent to your referring clinician, who will discuss findings with you.

When should I contact the clinic

Contact your GP or clinician promptly if the lump changes rapidly in size, becomes very painful, or if you develop other symptoms before your scan date.
