Radiology at the turn of the millennium.

Herein, the authors (a) review the status of the specialty; (b) report and analyze the various areas in which progress has occurred, namely, conventional radiology and picture archiving and communication systems (or PACS), ultrasonography, computed tomography, magnetic resonance imaging, interventional radiology, and nuclear medicine; and (c) discuss the problems radiology faces as it enters the new millennium. The problems are those facing medicine as a whole, as well as those threatening the future of radiology. These include the following: Will there be a need for radiologists in the future? Will radiology be too costly to be affordable? How can turf wars and fragmentation be solved? Possible remedies are suggested. Positive aspects are discussed in the light of the challenge to demonstrate value. Medical imaging is entering the new millennium with a solid record of recent advances in digital, cross-sectional, and interventional radiology. These advances have made the specialty indispensable in the treatment of patients. Careful statesmanship will be needed to solve the many problems that face medicine as a whole and radiology in particular.
