Abstract: An apparatus for identifying nuclear magnetic spectra from spatially selectable regions of an examination subject supplies pulse signals to the examination subject in the following sequence. A first, non-selective 90.degree. RF pulse is supplied to the patient so that the magnetization of the examination subject is oriented out of the z-direction into an x-y plane perpendicular thereto. A first, selective 180.degree. RF pulse is then supplied simultaneously with a first magnetic gradient G.sub.z which effects a dephasing of the spins outside of a first, selected slice S.sub.1. A second, selective 180.degree. RF pulse is then supplied simultaneously with a second magnetic gradient G.sub.x disposed perpendicularly to the first magnetic gradient. The second magnetic gradient effects a dephasing of the spins outside of a second selected slice S.sub.2. A second, selective 90.degree. RF pulse is then supplied simultaneously with a third magnetic gradient G.sub.
