A magnetic resonance imaging apparatus has a magnet with at least one patient receptacle and at least one support plate, as well as a predetermined number of transmit and/or receive coils. In at least two predetermined exposure positions, at least one exposure respectively takes place using predetermined adjustment parameters. High-contrast exposures can be obtained in a short time, by the required adjustment parameters being determined in a preceding adjustment process, and the exposures are carried out in a subsequent exposure process.
