Parallel imaging allows the reconstruction of images from undersampled multicoil data. The two main approaches are: SENSE, which explicitly uses coil sensitivities, and GRAPPA, which makes use of learned correlations in k‐space. The purpose of this work is to clarify their relationship and to develop and evaluate an improved algorithm. 
LORAKS makes better SENSE: Phase‐constrained partial fourier SENSE reconstruction without phase calibration
This work proposes and evaluates SENSE‐LORAKS, which enables combined parallel imaging and partial Fourier reconstruction without requiring prior phase information.
T2 shuffling: Sharp, multicontrast, volumetric fast spin‐echo imaging

Coil compression in simultaneous multislice functional MRI with concentric ring slice‐GRAPPA and SENSE
A coil compression method is proposed that works with concentric ring non‐Cartesian SMS imaging and should work with Cartesian SMS as well and is evaluated on fMRI scans of several subjects and compared to standard coil compression methods.

Accelerated T2 mapping combining parallel MRI and model‐based reconstruction: GRAPPATINI
Quantitative T2 measurements are sensitive to intra‐ and extracellular water accumulation and myelin loss and promise to be a good biomarker of disease, however, they require long acquisition times.
Robust autocalibrated structured low‐rank EPI ghost correction
A new structured low‐rank method for echo‐planar imaging (EPI) ghost correction called Robust Autocalibrated LORAKs (RAC‐LORAKS) is proposed and evaluated, which does not require conventional EPI navigator signals, and is robust to imperfect autocalibration data.

The problem of inaccurate coil sensitivities is addressed with a new non-linear algorithm for auto-calibrated parallel imaging, which allows for a reconstruction of artefact-free images with higher acceleration factors and less reference data than previous linear approaches.

This technique, GeneRalized Autocalibrating Partially Parallel Acquisitions (GRAPPA) is an extension of both the PILS and VD‐AUTO‐SMASH reconstruction techniques and provides unaliased images from each component coil prior to image combination.

The imaging data demonstrate that the coefficient penalized regularization method in GRAPPA reconstruction is able to reduce noise amplification to a greater degree and enhances the quality of images significantly when compared to the previous least squares and Tikhonov regularization methods.
An EigenVector Approach to AutoCalibrating Parallel MRI , Where SENSE Meets GRAPPA
A new way to compute the explicit sensitivity maps that are (implicitly) used by acPI methods is presented, which estimates them directly from the calibration matrix by Eigen-vector analysis of the k-space filtering in acPI algorithms.
