Abstract: In a method and apparatus for setting and/or adjusting scan parameters for a scan sequence of a magnetic resonance examination, manual selection of a scan parameter to be set is made, followed by setting and/or changing a value of the selected scan parameter to be set. At least one dependent scan parameter is determined in a computer, the value of which, on a change to a value of the scan parameter to be set, would undergo a change provided that existing image-acquisition criteria are retained. The computer also determines a suggested change for a change to the value of the at least one dependent scan parameter, and displays the at least one dependent scan parameter and the suggested change for a change to the value of the at least one dependent scan parameter.
