Method for operating a magnetic resonance imaging apparatus ensuring coincidence of images obtained in different examinations with respectively different positions of a subject

A method for operating a magnetic resonance apparatus, comprising the steps of:

• in a first examination of a subject in a first position in a magnetic resonance apparatus, obtaining a first scout dataset, representing magnetic resonance signals from said subject, and subsequently defining a first slice of said subject based on said first scout dataset;
• repositioning said subject to a second position, different from said first position, in said magnetic resonance apparatus and, in a further, subsequent examination of said subject in said magnetic resonance apparatus, obtaining a further scout dataset, representing magnetic resonance signals from said subject;
• identifying a change in said position of said subject between said first scout dataset and said further scout dataset;
• and
• defining a further slice of said examination subject dependent on said change in position, said further slice having an identical positioning within said subject as said first slice.
