Interventional radiology
Interventional Radiology (IR) is a subspecialty of Medical imaging (Radiology) in which minimally invasive procedures are performed using image guidance. Some of these procedures are done for purely diagnostic purposes (e.g., angiograms), while others are done for treatment purposes (e.g., angioplasties). Pictures (images) are used to direct these procedures, which are usually done with needles or other tiny instruments like small tubes called catheters.
