Diagnostic Ultrasound in Physical Therapy
Non-invasive, real-time imaging that helps guide your recovery with confidence.
See What’s Really Going On — Without Radiation, Without Guesswork
Diagnostic ultrasound allows licensed physical therapists to examine the inside of your body in real time and identify soft tissue injuries that may be causing pain. It is safe, radiation-free, and highly effective in supporting accurate diagnosis and personalized treatment.
What Is Diagnostic Ultrasound?
Diagnostic ultrasound is different from the therapeutic ultrasound that some patients may be familiar with. Instead of applying heat, it uses high-frequency sound waves to create live images of muscles, tendons, ligaments, and other soft tissues. The technology is similar to the ultrasound used during pregnancy but is applied to orthopedic and musculoskeletal conditions.
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
The ability to visualize the injury helps patients understand their condition and take a more active role in their recovery. It also allows physical therapists to make more informed decisions and tailor interventions based on what they see, rather than relying solely on symptoms or manual tests.
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
While it is not typically used to diagnose fractures or conditions deep in the spine, it can complement other imaging tools such as X-rays or MRIs, especially when immediate soft tissue evaluation is needed.
What to Expect During Your Appointment
During an ultrasound session, the physical therapist will review your symptoms and explain what they plan to assess. 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.
Appointments typically take 20 to 30 minutes. You may remain fully dressed except for the area being examined. The process is painless, though you might feel slight pressure where the probe touches sensitive areas. In many cases, the therapist will also compare the affected side with the opposite limb to better understand the condition.
You will leave the appointment with immediate insights into your injury and how it may impact your therapy plan. Follow-up scans may be used to track healing progress and make adjustments to your care.
Is It Safe? What About Insurance?
Diagnostic ultrasound is non-ionizing and completely safe. It involves no radiation and has no known side effects. It is appropriate for a wide range of patients, including those who are pregnant or have medical implants.
In terms of cost, the price of a diagnostic ultrasound is typically similar to that of a standard physical therapy visit. Coverage depends on your individual insurance plan, but in most cases, it is included as part of your therapy program. Our staff will verify your insurance benefits and let you know in advance what to expect.
A physician referral is usually not required. As licensed physical therapists, we are recognized as primary care providers for musculoskeletal conditions, meaning you can typically come directly to us for evaluation, diagnostic imaging, and treatment. However, it’s always a good idea to check with your insurance provider to understand your specific coverage and referral requirements.
A common exception where a referral is needed is workers’ compensation programs that require prior authorization.
Frequently Asked Questions
How is diagnostic ultrasound different from an MRI or X-ray?
Ultrasound is excellent for viewing soft tissues and provides live, real-time feedback. MRI is useful for deep or complex internal structures but is more expensive and not always available on short notice. X-rays show bones but are not effective for visualizing muscles or tendons.
Will I be able to see the images during the session?
Yes. The therapist will walk you through the imaging on screen and explain what is being seen. This helps patients better understand their condition.
Does it hurt?
No. At most, you may feel gentle pressure where the area is already tender, but the procedure itself is non-invasive and very comfortable.
Do I need a referral?
Not usually. Most patients can access physical therapy and diagnostic ultrasound directly without a referral, unless it is part of a workers’ compensation or specific insurance requirement.
