1. A method for acquiring magnetic resonance data, comprising the steps of: exposing a region of a subject to a spin-echo magnetic resonance pulse sequence comprising an excitation RF pulse and multiple refocusing RF pulses that exhibit a flip angle evolution, and that cause magnetic resonance signals to be emitted from the region as an echo train; prescribing said flip angle evolution to cause a signal evolution in said echo train resulting in contrast between tissues in said region; sampling a first part of said signal evolution to obtain a first set of k-space data with a non-T2-weighted first type of weighting of said contrast, and sampling a second part of said signal evolution to obtain a second set of k-space data with a second type of weighting of said contrast, until a desired number of contrast weightings are sampled; and making said first set of k-space data available as a first electronic output in a form from which a first image of said region can be generated with said non-T2-weighted first type of weighting of said contrast, and making said second set of k-space data available as a second electronic output in a form from which a second image of said region can be generated with said second type of weighting of said contrast, until all of said images of said region with said contrast weightings can be generated.
