Abstract:
1. A method for generating data representing T2-weighted images of tissue with short T2 time in magnetic resonance tomography imaging, comprising the steps of: operating a magnetic resonance data acquisition device to obtain magnetic resonance image data from a subject by exposing the subject to a steady-state free precession sequence with projection-reconstruction, in a plurality of sequence repetitions with a repetition time TR; in each sequence repetition, emitting non-slice-selective RF excitation pulses and, in each direction of a spatial coordinate system, emitting gradient pulses selected from the group consisting of bipolar pulses that are point-symmetrical at TR/2, and multi-polar gradient pulses that are axially symmetrical at TR/2, and that have a surface area for each axis comprising a total value of 0; in each sequence repetition, reading out a first steady-state signal as a True-FISP as a half echo with a short echo time TE making said magnetic resonance data available as an output from said magnetic resonance data acquisition device in a form allowing processing of said magnetic resonance data to generate a T2-weighted magnetic resonance image of the subject therefrom.
