Abstract
An object positioned in an examination volume of a magnetic resonance (MR) device () is T-weighted MR imaged such that the MR image is essentially free from interfering contributions from MR signals without Tweighting. The object () is subject to a first Tpreparation sequence (TPREP) including an excitation RF pulse (), one or more refocusing RF pulses (), and a tip-up RF pulse (). The object () is subject to a first readout sequence (RO) including at least one excitation RF pulse and switched magnetic field gradients for acquiring a first set of MR signals. The object () is subject to a second Tpreparation sequence (TPREP) including an excitation RF pulse ('), one or more refocusing RF pulses (′), and a tip-up RF pulse (′). At least one of the RF pulses (′) of the second Tpreparation sequence (TPREP) has a different phase than the corresponding RF pulse () of the first Tpreparation sequence (TPREP). The object () is subject to a second readout sequence (RO) 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.
