Interventional radiology uses minimally-invasive image-guided procedures to diagnose and treat diseases in nearly every organ system. For many conditions, interventional radiology offers an alternative to surgery. In addition, these procedures typically require shorter hospital stays and allow patients to recover and return to their normal daily activities faster than patients who have undergone surgery.
Using X-rays, CT, ultrasound, MRI, and other imaging modalities, interventional radiologists obtain images which are then used to direct interventional instruments throughout the body. These procedures are usually performed using needles and narrow tubes called catheters, rather than by making large incisions into the body as in traditional surgery.
