What is interventional radiology?
It is a specialty of radiology in which radiologists diagnose and/or treat diseases without surgery, by guiding tiny catheters through your body’s arteries and organs. This allows the radiologist to place medications directly at the organ site, open blocked blood vessels, drain an obstructed kidney, obtain biopsies, and perform many other procedures – using x-rays and other radiographic equipment for guidance. Interventional radiologists specialize in the use of fluoroscopy, CT, and ultrasound to guide their way through the skin by needle puncture, including introduction of wires and catheters for performing procedures such as biopsies, draining fluids, inserting catheters, or dilating or stenting narrowed ducts or vessels.
