title: How does magnetic resonance compare with computed tomography?
abstract: Magnetic resonance (MR) is a new technology that has benefited by transfer of technology already developed for computed tomography (CT), but many further changes should be expected in its technologic development. Already MR imaging in some instances equals or surpasses CT, and other less obvious advantages may become apparent. MR costs may not compare unfavorably with those of CT, and increased cost might still be justified if more information can be obtained or if the need for other tests or length of hospitalization could be reduced. The fact that MR at this stage might equal CT is a real accomplishment; this performance should be acknowledged and rapid development and scientific investigation of MR technology should be actively supported.
