What Is Diagnostic Ultrasound?

Diagnostic ultrasound is a tool physical therapists use to examine the inside of your body in real time. It uses high-frequency sound waves to create live images of muscles, tendons, ligaments, and other soft tissues. It is one of the safest imaging tools available, with no exposure to radiation and no known side effects. It is also suitable for nearly all patients, including those who are pregnant or have implanted medical devices.

Why Is Diagnostic Ultrasound Used in Physical Therapy?

Physical therapists use diagnostic ultrasound to:

• Confirm or clarify a diagnosis
• Determine the severity of an injury
• Guide the development of a treatment plan
• Monitor tissue healing over time

What Can It Help Diagnose?

Diagnostic ultrasound is particularly effective for evaluating soft tissue conditions such as:

• Rotator cuff issues
• Tendonitis and tendinosis
• Muscle strains or tears
• Ligament injuries
• Plantar fasciitis
• Patellar tendon problems
• Hip and shoulder impingements

What to Expect During Your Appointment

During an ultrasound session, a small handheld probe is applied to the skin over the affected area using a water-based gel. You and your therapist can view the images together in real time on a screen during an appointment that lasts about 20-30 minutes. You will remain fully dressed except for the area being examined. The process is painless and you will leave the appointment with immediate insights into your injury and how it may impact your therapy plan.

What About Insurance and a Referral?

The price of a diagnostic ultrasound is typically similar to that of a standard physical therapy visit. As primary care providers, you can come directly to us for evaluation, diagnostic imaging, and treatment, so a physician’s referral is usually not required. Coverage depends on your individual insurance plan, but our staff will verify your insurance benefits.
