title: Magnetic resonance imaging. Diffusion of technology in an ambulatory setting.
abstract: To better understand technology diffusion in an ambulatory care setting, we analyzed adult outpatients' use of magnetic resonance (MR) and computed tomography (CT) imaging in a group-model HMO between 1986 and 1989. The use of MR, but not CT, increased at a rapid pace with only a small proportion of the scans being accounted for by primary care physicians.
