Patent ID: 7725156

Claim:
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 1 , and reading out a second steady-state signal, separate from said first steady-state signal, as a T 2 -weighted True-FISP signal as a further half echo with a short echo time TE 2 =2 TR−TE 1 , and combining said half echo and said further half echo by weighted addition to obtain a magnetic resonance tomography image of tissue in said subject with very short T 2 time of approximately 1 millisecond, from said sequence repetitions; and 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.
