Claim:
1. A method to acquire magnetic resonance data comprising: (a) operating a magnetic resonance data acquisition unit, in which an examination subject is located, to radiate a spatially-selective excitation pulse, which is by itself spatially-selective, into the examination subject, said spatially-selective excitation pulse, by itself exciting nuclear spins at least in a selected region of the examination subject that is limited in three spatial directions, and thereby creating, at least with said spatially-selective excitation pulse, spin echo signals that originate only in said selected region; (b) after radiating the excitation pulse, operating the magnetic resonance data acquisition unit to radiate a series of at least two refocusing pulses into the examination subject, which generate variable flip angles adapted to a predetermined signal curve, with at least a second of said refocusing pulses in said series being radiated as a non-selective pulse; (c) operating the magnetic resonance data acquisition unit to acquire said spin echo signals as magnetic resonance data; (d) operating the magnetic resonance data acquisition unit to activate spatial coding gradients before and after radiating the spatially selective excitation pulse, the refocusing pulses, and during the acquisition of said spin echo signals; and (e) in a processor, processing the acquired magnetic resonance data to generate a data file, and making the data file available in electronic form at an output of said processor.
