What is the difference between Diagnostic Ultrasound & Therapeutic Ultrasound?

Diagnostic ultrasound also called diagnostic medical sonography is a non-invasive technique used to image organs inside the body using high-frequency sound waves that are above the audible range.

A camera or small handheld transducer along with a bit of gel is used on the skin to obtain the best images possible. These images are seen on a monitor and can provide valuable information for diagnosing and treating a variety of diseases and conditions.

Most examinations are performed using an ultrasound device outside the body but sometimes it involves placing a device inside your body.

Diagnostic ultrasound is a diagnostic tool used by Sonographers.
Therapeutic ultrasound also uses sound waves above the audible hearing range but does not produce images. Therapeutic ultrasound is applied using an ultrasound probe or transducer and a bit of gel just like diagnostic ultrasound.

The most common conditions treated with therapeutic ultrasound include soft tissue injuries such was tendonitis, non-acute joint swelling and muscle spasm. Most muscle and ligament injuries can benefit from therapeutic ultrasound to treat painful conditions and to promote tissue healing.

Therapeutic ultrasound is a treatment used by physiotherapists or occupational therapists.
