Abstract
In a method in the form of a single pulse sequence for operating a nuclear magnetic resonance tomography apparatus, suitable for use with a chronologically constant inhomogeneity of the basic magnetic field N radio-frequency excitation pulses (N<2), spaced with a time spacing T, are emitted onto an examination subject, under the effect of a magnetic field gradient in a first direction, the radio-frequency excitation pulses respectively having different frequency bands adjoining one another. Subsequently, radio-frequency refocusing pulses spaced with a time spacing of T/2 are emitted, with the nth radio-frequency excitation pulse and the nth radio-frequency refocusing pulse having respective frequency bands that substantially agree.
