Clinical activities of pediatric radiologists in the United States and Canada: 10-year follow-up.

The members of the Society for Pediatric Radiology were surveyed in 1989 about their involvement with newer imaging modalities. Results were compared with those obtained in a similar study performed 10 years earlier. The performance and monitoring of imaging studies increased dramatically, with most respondents now being involved with ultrasound (US) and computed tomography (CT), and almost one-half involved with magnetic resonance (MR) imaging. When equipment became available, pediatric radiologists were quicker to assume control of MR imaging than US and CT. In most large pediatric centers, imaging with all current modalities and of all organ systems has become the responsibility of pediatric radiologists. These findings are in contrast to those obtained in 1979, when pediatric imaging practices primarily consisted of conventional radiography and fluoroscopy.
