Interventional Radiology

Interventional radiology is a procedure whereby the Radiologist passes a needle into the region of interest under imaging guidance; usually ultrasound or computed tomography (CT). This may be for diagnostic reasons or for symptomatic relief of pain/discomfort.

The use of ultrasound or CT for interventional radiology increases the accuracy of needle placement thus minimising risk of complications. 

Intervention for Diagnostic Reasons

Interventional radiology for diagnostic reasons require the sampling of cells in the area of concern. 

Examples include:

  • Breast lesions
  • Thyroid nodules
  • Aspiration of fluid collections

The procedure will be performed using either ultrasound or CT. The Radiologist will pass a needle into the region of interest and collect tissue and/or fluid. The sample(s) will then be sent to a Pathologist for further analysis under a microscope. Finally a report will be sent to your referring doctor from the Pathologist detailing the cellular composition of the tissue collected.

Intervention for Symptomatic Relief

Interventional radiology for symptomatic relief requires the Radiologist to place a needle into the problem area and injecting medication directly into the area of concern.

Examples include:

  • Shoulder injections for inflammatory conditions such as bursitis
  • Spinal injections for pain relief

The procedure will be performed using either ultrasound or CT. A Radiologist report will be sent to your referring doctor outlining what was performed.
