Radiology continues to benefit from technological improvements by expanding the capabilities of imaging for clinical diagnosis and treatment. While no completely new procedure was accepted for clinical use in 1992, a variety of procedures that were adaptations of recently established technology demonstrated clinical efficacy. Five components of radiology are particularly important: (1) spiral computed tomography (CT), (2) interventional radiology, (3) two adaptations of magnetic resonance imaging (MRI)—magnetic resonance angiography (MRA) and functional MRI, (4) mammography, and (5) economics.

Although most observers thought that CT, which was introduced approximately 20 years ago, was a "mature" technology, the major adaptation of spiral CT has renewed clinical interest in the applications of CT. Spiral CT constantly images an anatomical region for as long as 30 seconds while the patient is transported through the detectors, creating a continuum of anatomical imaging. If conventional CT is thought of as an apple sliced in sections, spiral . . . [Full Text PDF of this Article]
