[Clinical applications of an instrument of resistive-type magnetic resonance of new design].
In Magnetic Resonance, resistive magnets give a poorer image quality than superconductive magnets, due to the lower magnetic field strength, uniformity and stability of resistive magnets. However, recent developments in resistive magnet technology have improved the field strength, as well as its uniformity and stability. The aim of this paper is to report the preliminary results of a new resistive magnet based on a iron core technology with transverse field orientation, operating at 0.38 T. The clinical experience based on about 200 studies of the brain, spinal cord, cervical, thoracic, lumbo-sacral spine, heart, abdomen and joints was promising in most clinical applications with results comparable to those of superconductive magnets with a similar field strength.
