Interventional radiologists are trained specialist in both diagnostic radiology and interventional therapy. Interventional radiology (IR) is a medical specialty that uses imaging modalities, such as fluoroscopy (live X-ray), CT, ultrasound, or MRI, to offer minimally invasive procedures for the diagnosis and treatment of a wide range of medical conditions.

These live images are used to guide the placement of small instruments, such as catheters or wires, through the skin and into the body to diagnose and treat diseases in nearly every organ system.
