Journal ArticleDOI
Calibrationless parallel imaging reconstruction based on structured low‐rank matrix completion
Peter J. Shin,Peter J. Shin,Peder E. Z. Larson,Peder E. Z. Larson,Michael A. Ohliger,Michael Elad,John M. Pauly,Daniel B. Vigneron,Daniel B. Vigneron,Michael Lustig +9 more
TL;DR: A calibrationless parallel imaging reconstruction method, termed simultaneous autocalibrating and k‐space estimation (SAKE), is presented, which is a data‐driven, coil‐by‐coil reconstruction method that does not require a separate calibration step for estimating coil sensitivity information.
Journal ArticleDOI
An introduction to coil array design for parallel MRI.
TL;DR: This review is intended to provide insight into how arrays are currently used for parallel MRI and to place into context the new innovations that are to come.
Journal ArticleDOI
Ultimate intrinsic signal-to-noise ratio for parallel MRI: electromagnetic field considerations.
TL;DR: The dependence of the ultimate intrinsic SNR on a variety of experimental conditions is explored and a physically intuitive explanation for the observed behavior is provided based on a comparison between the electromagnetic wavelength and the distance between aliasing points.
Journal ArticleDOI
Evidence Supporting LI-RADS Major Features for CT- and MR Imaging-based Diagnosis of Hepatocellular Carcinoma: A Systematic Review.

TL;DR: The quality of evidence supporting each LI-RADS major feature for diagnosis of HCC as well as of the LI- RADS imaging features suggesting malignancy other than HCC are assessed.
Journal ArticleDOI
Self-calibrating parallel imaging with automatic coil sensitivity extraction.
Charles A. McKenzie,Ernest N. Yeh,Michael A. Ohliger,Mark D. Price,Daniel K. Sodickson,Daniel K. Sodickson +5 more
TL;DR: This work shows that it is possible to extract sensitivity calibration images directly from a fully sampled central region of a variable‐density k‐space acquisition and these images have all the features of traditional PMRI sensitivity calibrations and therefore may be used for any PMRI reconstruction technique without modification.
