What is Diagnostic Ultrasound?
Musculoskeletal (MSK) ultrasound is a safe, non-invasive scan that uses high-frequency sound waves to produce real-time images of soft tissues: tendons, ligaments, nerves, bursae, the plantar fascia, and the fluid inside a joint. Unlike an X-ray, which shows bone, ultrasound excels at the soft-tissue structures that cause the majority of knee, foot, and ankle pain.
Its biggest advantage is that it is dynamic. We scan you in real time while you move the joint, so we can watch a tendon glide, stress a ligament, and see how a structure behaves under load. A static scan cannot do that. It means we assess function, not just anatomy.
At Lower Limb we use ultrasound as a core part of assessment rather than sending you elsewhere and waiting weeks for a report. You see the images on the screen with us, we explain what they show, and in most cases we start treatment the same day.
What We Scan
Knee

Ankle
We focus on musculoskeletal scanning of the lower limb. We do not perform abdominal, vascular, or pregnancy ultrasound.
Ultrasound or MRI?
For many soft-tissue problems in the knee, foot, and ankle, ultrasound is comparable to MRI, and for some it is the better test because it is performed in real time and assesses movement. It is also faster, lower cost, and available on the day rather than after a separate hospital appointment.
MRI still has its place. It is preferable for bone, cartilage, and structures deep within a joint. We are not here to sell you a scan for its own sake. If your problem is better answered by MRI or X-ray, we will tell you and help arrange it.
Ultrasound-Guided Injections
The same imaging that diagnoses your problem also lets us treat it accurately. When an injection is appropriate, performing it under real-time ultrasound means we watch the needle reach the exact target on screen, rather than injecting blind. Accuracy matters for both safety and results.
