Patent ID: 10732242

Abstract:
An object positioned in an examination volume of a magnetic resonance (MR) device (1) is T2-weighted MR imaged such that the MR image is essentially free from interfering contributions from MR signals without T2 weighting. The object (10) is subject to a first T2 preparation sequence (T2PREP1) including an excitation RF pulse (21), one or more refocusing RF pulses (22), and a tip-up RF pulse (23). The object (10) is subject to a first readout sequence (RO1) including at least one excitation RF pulse and switched magnetic field gradients for acquiring a first set of MR signals. The object (10) is subject to a second T2 preparation sequence (T2PREP2) including an excitation RF pulse (21′), one or more refocusing RF pulses (22′), and a tip-up RF pulse (23′). At least one of the RF pulses (21′, 22′, 23′) of the second T2 preparation sequence (T2PREP2) has a different phase than the corresponding RF pulse (21, 22, 23) of the first T2 preparation sequence (T2PREP1). The object (10) is subject to a second readout sequence (RO2) including at least one excitation RF pulse and switched magnetic field gradients for acquiring a second set of MR signals. The MR image is reconstructed from the first and second sets of MR signals.
