In a method and control system for producing two-dimensional diagnostic MR images using a magnetic resonance imaging scanner, a first three-dimensional MR image data set of a predetermined region within a body is produced using the magnetic resonance imaging scanner with an initial resolution. A second three-dimensional MR image data set of the predetermined region with a second resolution is then produced using the magnetic resonance imaging scanner, the second resolution being higher than the first resolution. Using the first three-dimensional MR image data set, layers are determined for the diagnostic two-dimensional MR images to be produced. The two-dimensional MR images are then computed from the second MR image data set for these layers automatically.
