Interventional Radiology FAQ

Interventional radiology combines image based diagnosis with minimally invasive therapy. The interventional radiologist is specialised in targeting treatment using imaging modalities such as X-ray, ultrasound and CT for guidance. Using non-surgical techniques, catheters can be guided through blood vessels or the skin directly to the source of the problem for direct treatment.

Identification of the problem can be made with angiography, ultrasound or x-ray, with the best access path being mapped out. By using the various catheters and stents, stenosed or short segmentally occluded arteries can be re-opened via the intra approach. With most blood vessels access is gained via groin or the arm.

Some of the benefits include:
• Most of the procedures can be performed on a short hospital stay or outpatient basis.
• Risk, pain and recovery time are often significantly reduced.
• A general anaesthetic is usually not required.
• Procedures can be less expensive than surgery or other alternatives.
