Abstract: A method and system for generating a magnetic resonance pulse sequence for the investigation of a sample by magnetic resonance, including generating a selective scan comprising an adiabatic inversion magnetic resonance pulse sequence wherein the magnetization is inverted from z to ?z inside a frequency band, following the selective scan with a non-selective scan comprising a CPMG magnetic resonance pulse sequence wherein the magnetization is maintained along z, obtaining a first signal from the selective scan, obtaining a second signal from the non-selective scan, and subtracting the first and second signals to obtain a resulting signal with only selected frequency components for slice selective investigation of the sample.
