1. A method, comprising:
obtaining k-space data of a spin echo magnetic resonance imaging (MRI) exam of subject, the k-space data comprising a plurality of echo train lengths (ETLs), each ETL comprising a subset of lines of the k-space data;
identifying a subset of ETLs of the plurality of ETLs of the k-space data corresponding to a dominant pose of the subject;
generating an undersampled version of the k-space data, the undersampled version including only the subset of ETLs;
entering the undersampled version of the k-space data as input to a reconstruction model trained to output a reconstructed image based on the undersampled version of the k-space data; and
displaying the reconstructed image on a display device and/or saving the reconstructed image in memory.
