A private musculoskeletal (MSK) ultrasound-scan at Victoria Medical uses high-frequency sound waves to produce real-time images of tendons, ligaments, muscles, joints, bursae, and peripheral nerves. It is the first-line imaging investigation recommended by BMUS and NICE for rotator cuff tears, tendinopathy, joint effusions, carpal tunnel syndrome, and soft tissue sports injuries — with the unique advantage of dynamic assessment that MRI cannot provide.
Shoulder pain that limits your reach, knee swelling after a twist, a heel that hurts with every step, or tingling fingers that wake you at night — these symptoms point to structures that ultrasound images with exceptional clarity. MSK ultrasound-scan is the only imaging modality that allows real-time dynamic assessment: the sonographer can move the joint during the scan to identify partial tears, impingement, and instability that appear normal on static MRI.
At Victoria Medical, our MSK sonographers hold postgraduate qualifications in musculoskeletal ultrasound and work in accordance with BMUS and European Society of Musculoskeletal Radiology (ESSR) guidelines. Dr Xynopoulos reviews all findings and can arrange a same-day sports medicine or orthopaedic referral if your results require further management. We are at 170 Vauxhall Bridge Road, London SW1V 1DX — two minutes from Victoria Station.

What Is an MSK Ultrasound-Scan?
A musculoskeletal ultrasound-scan uses high-frequency transducers — typically 10 to 18 MHz — to generate high-resolution images of superficial soft tissue structures. The higher the frequency, the greater the resolution for superficial structures such as tendons and peripheral nerves. Lower frequencies (5–10 MHz) are used for deeper structures such as the hip joint and gluteal tendons.
Unlike MRI, which produces static images in a fixed position, MSK ultrasound-scan enables dynamic assessment. The sonographer can ask you to move the joint, contract the muscle, or apply stress to a ligament during the scan — revealing pathology that only becomes apparent under load or movement. This dynamic capability is particularly valuable for diagnosing partial tendon tears, subacromial impingement, snapping tendons, and ligament instability.
MSK ultrasound-scan is also used to guide therapeutic injections — corticosteroid, hyaluronic acid, or platelet-rich plasma — with precision that landmark-guided injection cannot match. Ultrasound-guided injection is associated with significantly higher accuracy and improved clinical outcomes compared with unguided injection.
What Can an MSK Ultrasound-Scan Detect?
The table below summarises the main anatomical regions, conditions assessed, and the clinical relevance of MSK ultrasound-scan findings.
Dynamic advantage: MSK ultrasound-scan is the only imaging modality that allows real-time assessment of joint movement, tendon gliding, and impingement — findings that may be missed on static MRI.
| Region | Conditions Assessed | Clinical Relevance |
|---|---|---|
| Shoulder | Rotator cuff tears (full/partial thickness), subacromial bursitis, biceps tendon pathology, AC joint arthropathy, calcific tendinitis | Pooled sensitivity 95%, specificity 72% for rotator cuff tears (Liang et al., 2020); non-inferior to MRI for supraspinatus and infraspinatus |
| Knee | Meniscal cysts, patellar tendinopathy, quadriceps tendon tears, Baker's cyst, joint effusion, iliotibial band syndrome | Joint effusion characterised and aspirated under ultrasound guidance; Baker's cysts reliably detected and measured |
| Ankle & foot | Achilles tendinopathy, Achilles tears, plantar fasciitis, peroneal tendon tears, ankle ligament injuries | Achilles tendon thickness and echogenicity assessed; plantar fascia thickness >4 mm supports plantar fasciitis diagnosis |
| Elbow | Lateral epicondylitis (tennis elbow), medial epicondylitis (golfer's elbow), distal biceps tears, olecranon bursitis | Tendon echogenicity, thickness, and neovascularity assessed; guides injection therapy |
| Wrist & hand | Carpal tunnel syndrome (median nerve cross-sectional area), de Quervain's tenosynovitis, trigger finger, ganglion cysts | Median nerve CSA >10 mm² at the pisiform level supports carpal tunnel syndrome diagnosis |
| Hip | Greater trochanteric pain syndrome, gluteal tendon tears, iliopsoas bursitis, hip joint effusion | Dynamic assessment distinguishes snapping iliopsoas from snapping iliotibial band |
| Soft tissue masses | Lipomas, ganglia, foreign bodies, haematomas, nerve sheath tumours | Characterises benign vs indeterminate lesions; guides biopsy planning |
Rotator Cuff Assessment: What the Evidence Shows
Shoulder pain is one of the most common musculoskeletal presentations in primary care, and rotator cuff pathology accounts for the majority of cases. MSK ultrasound-scan is the recommended first-line imaging investigation for suspected rotator cuff disease.
A 2020 systematic review and meta-analysis in Medical Ultrasonography (Liang et al.) analysed seven prospective studies (n = 868 patients, 554 rotator cuff tears) and reported pooled sensitivity of 95% (95% CI: 88–98%) and specificity of 72% (95% CI: 61–81%) for rotator cuff tears, with an area under the SROC curve of 89%. The study confirmed that ultrasound is a high-efficiency diagnostic tool for rotator cuff tears, with high sensitivity making it suitable for ruling out significant pathology.
A 2020 prospective study in the Archives of Bone and Joint Surgery (Aminzadeh et al.) reported sensitivity of 93.7% for full-thickness rotator cuff tears and 90% for tendinopathy, with specificity of 100% for full-thickness tears and 96.7% for partial-thickness tears — using MRI as the reference standard.
A 2019 prospective study in PLoS ONE (Wengert et al.) compared high-resolution ultrasound with MR arthrography in 67 patients with suspected shoulder pathology. Consistency between the two modalities was 71.64% for the supraspinatus tendon, 95.52% for the infraspinatus tendon, and 83.58% for the subscapularis tendon. The study concluded that high-resolution ultrasound is a reliable imaging modality for the rotator cuff and recommended it as the preferred first-line tool over MRA for rotator cuff and biceps tendon assessment.
Tendinopathy and Tendon Injury Assessment
Tendinopathy — the clinical syndrome of tendon pain, swelling, and impaired function — affects tendons throughout the body and is a common presentation in both athletes and sedentary individuals. MSK ultrasound-scan assesses four key parameters: echogenicity (structural integrity), thickness, vascularity (neovascularisation), and calcification.
A 2025 systematic review in Ultrasound in Medicine & Biology (Gould et al.) identified echogenicity and thickness as the most commonly used ultrasound parameters for diagnosing rotator cuff tendinopathy, used in 88% of included studies. Vascularity was assessed in 50% of studies, with an ordinal scale used in all cases — reflecting the clinical importance of neovascularisation as a marker of active tendinopathy.
Ultrasound elastography — which measures tissue stiffness — adds a further dimension to tendon assessment. A 2018 review in Insights into Imaging (Prado-Costa et al.) concluded that both compression elastography and shear-wave elastography increase diagnostic sensitivity for tendinopathy compared with conventional ultrasound alone, and can detect pathological changes before they are visible on standard B-mode imaging.
Carpal Tunnel Syndrome and Peripheral Nerve Assessment
Carpal tunnel syndrome (CTS) — compression of the median nerve at the wrist — affects approximately 3–6% of the adult population and is the most common peripheral nerve entrapment syndrome. MSK ultrasound-scan measures the cross-sectional area (CSA) of the median nerve at the level of the pisiform bone.
A median nerve CSA greater than 10 mm² at the pisiform level supports the diagnosis of CTS, with sensitivity of approximately 77% and specificity of 87% compared with nerve conduction studies. Ultrasound has the additional advantage of identifying structural causes of nerve compression — such as ganglia, anomalous muscles, or tenosynovitis — that nerve conduction studies cannot detect.
Beyond the wrist, MSK ultrasound-scan assesses ulnar nerve entrapment at the elbow (cubital tunnel syndrome), common peroneal nerve compression at the fibular head, and Morton's neuroma in the forefoot.

| Claustrophobia | No issue | Can be problematic |
| Best for | Tendons, ligaments, nerves, bursae, joint effusions, guided injections | Bone marrow, cartilage, labrum, deep ligaments, spinal cord |
How to Prepare for Your MSK Ultrasound-Scan
No fasting or special preparation is required for an MSK ultrasound-scan. Wear comfortable clothing that allows easy access to the area being scanned. For a shoulder scan, a vest top or loose-fitting shirt is ideal. For a knee or ankle scan, shorts or trousers that roll up above the knee are appropriate.
Bring any previous imaging — X-rays, MRI reports, or previous ultrasound reports — to your appointment. This allows your sonographer to compare findings and focus the assessment on areas of clinical concern.
If you are attending for an ultrasound-guided injection, you may be asked to arrange for someone to drive you home, as the injected area may be temporarily numb or uncomfortable.
The Clinical Evidence Base
MSK ultrasound-scan is supported by an extensive evidence base across multiple anatomical regions and pathological conditions.
Liang et al. (2020, Medical Ultrasonography) — systematic review and meta-analysis of seven prospective studies (n = 868) — reported pooled sensitivity of 95% and specificity of 72% for rotator cuff tears, with SROC AUC of 89%. The study concluded that ultrasound is a high-efficiency diagnostic tool for rotator cuff tears and can be used as a first-line investigation.
Aminzadeh et al. (2020, Archives of Bone and Joint Surgery) — prospective study of 48 patients — reported sensitivity of 93.7% for full-thickness rotator cuff tears and 90% for tendinopathy, with specificity of 100% for full-thickness tears. The study used ESSR guidelines for protocol design.
Wengert et al. (2019, PLoS ONE) — prospective study of 67 patients comparing high-resolution ultrasound with MR arthrography — found moderate to almost perfect agreement between the two modalities for a wide range of shoulder pathologies. The study recommended high-resolution ultrasound as the preferred first-line tool for rotator cuff, biceps tendon, and acromioclavicular joint assessment.
Prado-Costa et al. (2018, Insights into Imaging) — systematic review of ultrasound elastography for tendon pathology — concluded that both compression elastography and shear-wave elastography increase diagnostic sensitivity for tendinopathy compared with conventional ultrasound alone, and can detect pathological changes before they are visible on standard B-mode imaging.
Gould et al. (2025, Ultrasound in Medicine & Biology) — systematic review of eight studies — identified echogenicity and thickness as the most commonly used ultrasound parameters for diagnosing rotator cuff tendinopathy, and highlighted the need for standardised assessment protocols to improve repeatability and comparability.
