Recent studies have shown that high quality phase
sensitive inversion recovery (PSIR) data can be
efficiently acquired at high magnetic field strengths
using a 3D interleaved sequence in which two separate
Turbo Field Echo (TFE) readouts are applied after each
inversion pulse. We propose that the phase data
associated with the second TFE readout of the PSIR
sequence can be used to form 3D maps of magnetic
susceptibility via the recently developed quantitative
susceptibility mapping (QSM) technique. The results
presented in this article demonstrate that T1-weighted
anatomical images and iron-sensitive QSM data can be
acquired simultaneously from a single scan.
