DOI: 10.1002/mrm.29672
Abstract: Conventional 3D Look‐Locker inversion recovery (LLIR) T1 mapping requires multi‐repetition data acquisition to reconstruct images at different inversion times for T1 fitting. To ensure B1 robustness, sufficient time of delay (TD) is needed between repetitions,… read more here.

DOI: 10.1002/nbm.4826
Abstract: Proton resonance frequency shift (PRFS) is currently the gold standard method for magnetic resonance thermometry. Yet, the linearity between the temperature-dependent phase accumulation and the static magnetic field B0 confines its use to rather high-field… read more here.

DOI: 10.1016/j.jmr.2021.107123
Abstract: Measurement of longitudinal-transverse (T1-T2*) relaxation may be time-consuming for samples with a long T1 lifetime. In this work, a fast measurement method of T1*-T2* relaxation correlation was presented based on a saturation recovery Look-Locker sequence.… read more here.
