Musculoskeletal Ultrasound
High-resolution, real-time ultrasound imaging of muscles, tendons, ligaments, joints, and peripheral nerves — providing dynamic diagnostic clarity that complements MRI and guides targeted treatment.
Advanced MSK Imaging Technology
Musculoskeletal (MSK) ultrasound uses high-frequency sound waves to produce detailed, real-time images of soft tissue structures throughout the body. Unlike MRI, MSK ultrasound is dynamic — it can capture structures in motion, allowing our specialists to assess tendons, ligaments, and muscles under functional conditions. It is also ideal for guiding diagnostic and therapeutic injections with precision.
What We Image & Diagnose
Tendon & Ligament Pathology
High-resolution imaging of tendon tears, tendinosis, and ligament injuries. MSK ultrasound can detect partial and full-thickness tears, calcific deposits, and peritendinous inflammation with exceptional detail.
- Rotator cuff tears
- Achilles tendinopathy
- Patellar tendon pathology
- Lateral epicondylitis
- Plantar fasciitis
Nerve Entrapment & Peripheral Nerves
Ultrasound visualization of peripheral nerves allows direct assessment of nerve caliber, echogenicity, and surrounding structures. Particularly valuable for confirming and localizing nerve entrapment syndromes.
- Carpal tunnel syndrome
- Ulnar nerve entrapment
- Tarsal tunnel syndrome
- Meralgia paresthetica
- Morton's neuroma
Joint Assessment
Real-time evaluation of joint effusions, synovitis, cartilage integrity, and bursitis. MSK ultrasound provides immediate, bedside assessment of joint pathology without radiation exposure.
- Joint effusion
- Synovitis and bursitis
- Baker's cyst
- Ganglion cysts
- Labral pathology
Ultrasound-Guided Dry Needling
Ultrasound-guided dry needling combines the precision of real-time ultrasound imaging with the therapeutic technique of dry needling. By visualizing the needle and target tissue simultaneously, Dr. Cahoon can accurately place the needle into specific structures — such as trigger points, tendons, or fascial layers — with a level of precision not possible with landmark-based techniques alone. This approach improves safety, enhances accuracy, and allows treatment of deeper or more complex structures that would otherwise be difficult to target.
- Trigger point dry needling with real-time needle visualization
- Tendon and peritendinous dry needling
- Deep muscle and fascial layer targeting
- Nerve hydrodissection combined with dry needling
- Post-procedure confirmation of needle placement
Why MSK Ultrasound?
Dynamic Imaging
Assess structures in real time and in motion — something static MRI cannot provide.
No Radiation
Safe for all patients including pregnant women and those requiring repeated imaging.
High Resolution
Superior soft tissue resolution for superficial structures compared to MRI.
Guided Precision
Direct needle visualization for injections and aspirations improves accuracy and safety.
Rapid Results
Immediate interpretation and prompt reporting to referring physicians.
Cost-Effective
Often a more accessible and cost-effective alternative or complement to MRI.
What to Expect
Physician Referral Required
All MSK ultrasound studies must be ordered by your physician. Bring your referral and any prior imaging reports to your appointment.
No Special Preparation
Most MSK ultrasound studies require no special preparation. Wear comfortable clothing that allows easy access to the area being examined.
The Examination
A handheld transducer is moved over the skin with ultrasound gel. The examination is painless and typically takes 20–45 minutes. You may be asked to move the area being examined to assess dynamic function.
Results & Reporting
Our specialist interprets your study immediately and prepares a detailed report. Results are sent promptly to your referring physician for clinical correlation and treatment planning.
Schedule Your MSK Ultrasound
A physician referral is required for all musculoskeletal ultrasound studies. If your physician has referred you, contact us to schedule your appointment. We serve patients throughout Lillington, NC and the surrounding region.
