Image Guided Procedures

At Imaging Associates Wagga Wagga we are happy to offer injections and procedures which may be guided under CT or Ultrasound. These may include:

Spinal Injections

Nerve Root Injection
Nerve Roots may become inflamed when impinged or compressed by a bulging disc. Occasionally, an imaging study (e.g. MRI) may not clearly show which nerve is causing the pain and a nerve root injection is performed to assist in isolating the source of pain. In addition to its diagnostic function, this type of injection may offer the patient some pain relief.

Facet Joint Injection
A facet joint is a small joint of the spine that provides stability and help guide motion. These joints are found in the neck, upper and lower back regions. These joints become painful due to arthritis, injury or mechanical stress. A cortisone injection reduces inflammation and provide long lasting pain relief from 3-6 months. Results vary from person to person.

Epidural  
An epidural injection is where a mixture of a local anaesthetic and a steroid, such as cortisone, is injected into the space surrounding the spinal cord (epidural space). 

Epidural injections are useful to settle down pain that is associated with inflammation within the lumbar spinal canal. The epidural space is the fat containing area between the outside lining of the spinal cord (dura) and the spinal canal.

Pain relief can sometimes be obtained with this technique for acute lumbar disc herniations and occasionally with acute discogenic pain. For reasons that are not entirely understood it may also provide relief for some sufferers of spinal stenosis. Epidurals can also be used to diminish neural tension and hence can be used for hamstring and calf dysfunction.

Women’s Health

Hookwire Localisation/Insertion
Sometimes our scans show abnormalities in the breast. If the abnormality is to be surgically removed, it is necessary to place a fine wire, called a hookwire, in the breast with its tip at the site of the abnormality. This acts as a marker during surgery and enables the surgeon to remove the correct area of breast tissue. The hookwire is inserted to guide the removal of both benign (non-cancerous) and malignant (cancerous) abnormalities. Mammography or ultrasound are used by our radiologist to place the hookwire into the correct position. The wire is called a hookwire because there is a tiny hook at the end, which keeps it in position. Breast Hookwire Localisation is done using local anaesthetic to numb the breast in the area where the hookwire is to be inserted.

Fine Needle Aspiration
Ultrasound-guided fine needle aspiration uses ultrasound to locate a problem area, followed by insertion of a small-gauge needle to area to withdraw cells for pathologic evaluation.

Stereotactic and tomosynthesis guided breast biopsies
A stereotactic core biopsy is another method used to sample abnormal tissue identified on a mammogram. During the procedure, the breast is compressed similar to a mammogram. Following local anesthesia, a small nick is made in the skin of the breast and a needle is inserted to obtain multiple samples of breast tissue for laboratory analysis.

Musculoskeletal Injections

Hydrodilatation
This is a common treatment for frozen shoulder (adhesive capsulitis) or impingement. Using x-ray guidance, this injection aims to stretch the joint capsule to decrease pain and increase function of the shoulder.Joint

Joint Injections
Cortisone is powerful anti-inflammatory medication. Commonly used to treat pain in various parts of the body including inflamed joints, tendons and bursa. These injections are often preformed under ultrasound or x-ray. Common joints treated include the ankle, knee, shoulder, elbow, hip, spine, and wrist.

Autologous Blood Injection (ABI)
An injection of your own blood into tendons and muscles to stimulate a healing response.

Platelet Rich Plasma (PRP) Injection
Similar to an ABI, a PRP is an injection of your own blood that has been centrifuged to separate the blood into components. The Platelets and Plasma are full of growth factors that are injected into the problem area to stimulate a healing response. Most commonly used in tendons, muscles and joints.
