Ultrasound Imaging

Ultrasound Imaging is a medical imaging technique that uses high-frequency Sound Waves to create images of structures inside the body, based on the echoes that bounce back from tissue. It doesn't use ionising radiation.

In breast cancer detection, it's often used alongside Mammography, particularly for dense breast tissue, and to tell whether a lump is a fluid-filled cyst or a solid mass.
