About this service
Our radiologists perform a range of image-guided interventional procedures, therapeutic injections, biopsies, aspirations and drainages, using ultrasound or CT guidance for accuracy and safety.
What to expect
The radiologist explains the procedure and obtains your consent. Skin is cleaned and local anaesthetic is given. The procedure is performed under live imaging guidance. Most injections take 15–30 minutes including recovery.
Procedures we perform
Every procedure is performed by a sub-specialist radiologist using live ultrasound or CT guidance, so medication is placed exactly where it is needed.
Facet joint injection
Helps with: Back and neck pain from arthritic or inflamed facet joints
Cortisone is placed precisely into the small joints at the back of the spine to settle inflammation.
Relief often lasts 3 to 6 months
Epidural injection
Helps with: Back pain, sciatica and spinal canal stenosis
Cortisone is delivered into the epidural space, most commonly in the lower (lumbar) spine, to reduce nerve irritation.
Nerve root injection
Helps with: Radiating arm or leg pain, pins and needles, numbness
A targeted cortisone and anaesthetic injection beside an irritated nerve root to calm inflammation and pain.
Joint injection
Helps with: Arthritis and synovitis of the hip, knee, shoulder and smaller joints
Local anaesthetic followed by cortisone, placed directly into the joint for pain relief and reduced inflammation.
Hydrodilatation
Helps with: Frozen shoulder (adhesive capsulitis)
A larger volume of saline with cortisone gently stretches the tight shoulder capsule to restore movement.
Bursal injection
Helps with: Bursitis of the shoulder, hip and other sites
Cortisone is placed into an inflamed bursa, the fluid cushion between tendon and bone.
Tendon sheath injection
Helps with: Tenosynovitis, trigger finger, plantar fasciitis
Precise injection around an inflamed tendon or fascia while avoiding the tendon itself.
Ganglion and Baker cyst aspiration
Helps with: Painful or enlarged fluid-filled cysts
Fluid is drawn out of the cyst through a fine needle, often followed by a cortisone injection.
Fine needle aspiration (FNA)
Helps with: Thyroid nodules, lymph nodes and other lumps
A very fine needle collects cells for pathology, helping your doctor reach a diagnosis.
Core biopsy
Helps with: Breast, soft tissue and other masses needing a tissue diagnosis
A small sample of tissue is taken under local anaesthetic for detailed pathology testing.
Tell us if you take blood thinners, are pregnant or have known allergies. Specific preparation depends on the procedure, our team will brief you when booking.
Results and reports
