title: Technological advances in radiology.
abstract: This overview examines the principles underlying modern diagnostic imaging techniques already in use and those expected in the near future. As new techniques have become accepted, older ones such as air studies have been dispensed with. Although many of the new modes appear expensive, they give the doctor an opportunity to effect large cost savings to the community if he employs them wisely.
