Interventional Radiology is a clinical subspecialty of Radiology. Interventional Radiologists apply minimally invasive therapies using imaging guidance such as X-ray, ultrasound and CT scan. Many conditions that once required surgery can be treated non surgically by Interventional radiologists.

The procedures are typically performed using a percutaneous approach (via a small nick through the skin).Tiny catheters and miniature instruments are used, these are so small they can be run through a patient’s network of arteries to treat directly at the site of illness internally. Most procedures are performed under local anaesthetic, however Intravenous sedation and pain control may be required in some procedures. Interventional Radiology is generally associated with low complication rates, and the recovery period is usually shorter than when open surgery is performed.
