The short answer
Musculoskeletal (MSK) ultrasound can examine many tendons, muscles, superficial ligaments, joints and nerves. It can help investigate some tears, inflammation and fluid collections. It cannot answer every question about pain: bone blocks ultrasound, and some deep structures are difficult to assess. The right investigation depends on what the clinician is trying to find out. [1]
What might an MSK scan help investigate?
Examples include a suspected rotator cuff tendon tear at the shoulder, an Achilles tendon problem, swelling around a joint, or selected nerve entrapments. Ultrasound also allows moving structures to be viewed in real time. These are examples of possible uses, not a promise that every condition can be diagnosed during every scan. [1]
What are the limitations?
Ultrasound does not give a complete view inside bone. MRI or another investigation may be needed for structures that ultrasound cannot adequately examine. Depth can also limit image quality. A scan should be chosen to answer a specific clinical question rather than on the assumption that one type of imaging is always best. [1]
What happens at the appointment?
For an external ultrasound, a practitioner places gel on the skin and moves a handheld probe over the area. You may be asked to change position. Preparation depends on the examination, so follow the clinic's instructions rather than fasting or changing medication on your own. Ultrasound uses sound waves and does not use X-rays. [2]
Bring the details of previous investigations and a list of questions. If you have had a recent injury, explain when it happened, how symptoms have changed and what you can no longer do comfortably. Ask the clinic in advance whether the booked examination covers the area and question you want assessed.
Five questions to ask before booking
1. What specific question will this scan answer?
2. Is ultrasound appropriate for the structure being investigated?
3. Who will perform and interpret the scan, and what relevant training do they have?
4. How and when will I receive the report, and who will explain the findings?
5. What happens if the scan does not explain my symptoms or another test is needed?
Questions patients often ask
Is an ultrasound scan the same as ultrasound treatment?
No. This article describes diagnostic imaging: a test used to obtain images. A booking for imaging should not be understood as a treatment session. Confirm exactly what your appointment includes. [1,2]
Will I receive my results immediately?
Results arrangements differ between services. The NHS explains that you may receive information during the appointment or need to wait for the results to reach the referring professional. Confirm your clinic's reporting arrangements before booking. [2]
Is a normal scan the end of the assessment?
Ask the clinician how the findings relate to your symptoms and what the next step is. The limitations above are why a scan report should be discussed in the context of the question it was intended to answer. [1]
What is a musculoskeletal ultrasound scan?
A musculoskeletal, or MSK, ultrasound scan uses sound waves to produce real-time images of selected muscles, tendons, ligaments, joints, nerves and other superficial soft tissues. It does not use X-rays.
What problems can an MSK ultrasound help investigate?
Depending on the area and clinical question, ultrasound may help investigate tendon problems, selected tears, bursitis, joint fluid, muscle injuries, cysts and certain nerve entrapments. Its suitability depends on the structure being examined.
Can an ultrasound scan replace an MRI?
Not always. Ultrasound is useful for many superficial soft tissues and for viewing movement in real time, while MRI may be more appropriate for deeper structures, the inside of bone or areas that ultrasound cannot adequately assess.
Does an MSK ultrasound scan use radiation?
No. Diagnostic ultrasound uses sound waves and does not use ionising radiation.
Do I need a GP referral for an ultrasound at Ben Cohen Osteopathy?
No GP referral is required for the diagnostic musculoskeletal ultrasound service at Ben Cohen Osteopathy. The scan should still be selected to answer an appropriate clinical question.
How quickly will I receive my ultrasound report?
Ben Cohen Osteopathy normally provides a written report within 24 hours. The findings should be considered alongside your symptoms and clinical assessment.
How do I know whether ultrasound is the right next step?
The right investigation depends on the body area, the structures involved and the question that needs answering. If you are unsure, everyone is welcome to email ben@bencohenosteopathy.com before booking so the team can help you understand whether ultrasound, an osteopathic assessment or another route may be more appropriate.
