What Is Diagnostic Ultrasound?
Diagnostic ultrasound is a safe, non-invasive imaging technology used to evaluate soft tissues, tendons, ligaments, nerves, and joints in the foot and ankle. Using high-frequency sound waves, ultrasound creates real-time images that allow podiatrists to accurately diagnose a wide range of foot and ankle conditions.
At St. Louis Foot & Ankle, diagnostic ultrasound helps our specialists quickly identify the source of your pain so we can develop an effective treatment plan.
Conditions Diagnosed With Foot & Ankle Ultrasound
Diagnostic ultrasound is particularly helpful for evaluating soft tissue injuries and inflammation that may not appear clearly on X-rays. It may be used to diagnose:
- Plantar fasciitis
- Tendon injuries and tears
- Achilles tendonitis
- Ligament sprains
- Soft tissue masses or cysts
- Bursitis
- Nerve entrapment conditions
- Morton’s neuroma
- Inflammation around joints
Because ultrasound imaging provides real-time visualization, it also helps doctors observe how tissues move during foot or ankle motion.
Benefits of Diagnostic Ultrasound
Diagnostic ultrasound offers several advantages for patients:
Non-invasive and painless
No incisions, needles, or injections are required for the imaging itself.
Radiation-free imaging
Unlike X-rays or CT scans, ultrasound uses sound waves rather than radiation.
Real-time imaging
Doctors can observe tissue movement during examination for improved accuracy.
Quick and convenient
Most ultrasound exams can be completed during a regular office visit.
Guided treatment
Ultrasound can assist physicians when performing injections or other treatments by ensuring precise placement.
What to Expect During Your Ultrasound Exam
During your ultrasound examination:
- A small amount of gel is applied to the skin over the area being examined.
- A handheld device called a transducer is moved across the skin.
- Sound waves create images that appear instantly on a monitor.
- Your doctor evaluates the images and discusses findings with you.
The procedure is painless and usually takes 15–30 minutes.
When Should You Consider Diagnostic Ultrasound?
You may benefit from diagnostic ultrasound if you experience:
- Persistent heel or foot pain
- Swelling or inflammation in the foot or ankle
- Suspected tendon or ligament injury
- Limited mobility or stiffness
- Pain that has not improved with initial treatment
Accurate imaging is an important step toward identifying the cause of your symptoms and selecting the most effective treatment.
