Ultrasound is a type of diagnostic test where a probe is moved over your body by a sonographer to obtain images of your internal structures. It is particularly good at characterising superficial structures. Ultrasound can characterise body parts while they are moving, and also assess blood flow (Doppler).
Ultrasound can be used to assess any superficial and many soft tissue structures, including the eyes, the brain and stomach in newborns, and sites of injury to assess for foreign bodies or infection. These are some of the more commonly performed scans.
Interventional treatments offered under ultrasound include:
• Musculoskeletal corticosteroid injection
• Nerve blocks
• PRP or whole blood injection
• Trigger point injection
Ultrasound contains no ionising radiation, and presents no significant risk.
