Interventional radiology: reflections and expectations. The 1985 Eugene P. Pendergrass new horizons lecture.

The history and current practice of interventional radiology are reviewed. Interventional radiology is considered a subspecialty of diagnostic radiology that involves the use of a variety of percutaneous techniques to treat a spectrum of vascular and nonvascular diseases. It is physician intensive and requires a commitment to patient care analogous to that in surgery. Still considered in its infancy, interventional radiology should prosper and undergo continued growth over the next several decades.
