Phase wraps fat chemical shift removed a graph‐cut‐based phase analysis IDEAL an iterative approach. The large range air lungs blood heart was...
Typical quantitative susceptibility mapping (QSM) reconstruction steps consist of first estimating the magnetization field from gradient-echo images, and then reconstructing map estimated field. The errors field-estimation may propagate into final QSM map, noise in no longer be zero-mean Gaussian noise, thus, causing streaking artifacts resulting QSM. A multiecho complex total inversion (mcTFI) method was developed to compute directly gradient echo images using an improved signal model that...

The inversion from the magnetic field to susceptibility distribution is ill-posed because dipole kernel, which relates field, has zeroes at a pair of cone surfaces in k-space, leading streaking artifacts on reconstructed quantitative maps (QSM). A method impose consistency data (CCD) with structural priors proposed improve solutions k-space methods.The information region recovered by enforcing prior, while noncone trust enforced be consistent measurements k-space. This CCD was evaluated...
Quantitative susceptibility mapping (QSM) of human spinal vertebrae from a multi‐echo gradient‐echo (GRE) sequence is challenging, because comparable amounts fat and water in the make it difficult to solve nonconvex optimization problem fat‐water separation (R2*‐IDEAL) for estimating magnetic field induced by tissue susceptibility. We present an in‐phase (IP) echo initialization R2*‐IDEAL QSM vertebrae. Ten healthy subjects were recruited spine MRI. A 3D GRE was implemented acquire out‐phase...
