Metal-Induced Artifacts in MRI
Brian A. Hargreaves,Pauline W. Worters,Kim Butts Pauly,John M. Pauly,Kevin M. Koch,Garry E. Gold +5 more
TL;DR: The presence of metallic implants in MRI can cause substantial image artifacts, including signal loss, failure of fat suppression, geometric distortion, and bright pile-up artifacts.
Journal ArticleDOI
SEMAC: Slice Encoding for Metal Artifact Correction in MRI
TL;DR: The efficacy of the SEMAC technique in eliminating metal‐induced distortions with feasible scan times is validated in phantom and in vivo spine and knee studies.
Journal ArticleDOI
Water-fat separation with IDEAL gradient-echo imaging.
Scott B. Reeder,Charles A. McKenzie,Angel R. Pineda,Huanzhou Yu,Ann Shimakawa,Anja C. S. Brau,Brian A. Hargreaves,Garry E. Gold,Jean H. Brittain +8 more
TL;DR: To combine gradient‐echo (GRE) imaging with a multipoint water–fat separation method known as “iterative decomposition of water and fat with echo asymmetry and least squares estimation” (IDEAL) for uniform water-fat separation, the IDEAL technique is introduced.
Journal ArticleDOI
Design and analysis of a practical 3D cones trajectory.
TL;DR: An algorithm is presented that generates the 3D Cones gradient waveforms given a desired field of view and resolution and the resulting trajectory is very signal‐to‐noise ratio (SNR) efficient and has excellent aliasing properties.
Journal ArticleDOI
Improved Pediatric MR Imaging with Compressed Sensing
Shreyas S. Vasanawala,Marcus T. Alley,Brian A. Hargreaves,Richard A. Barth,John M. Pauly,Michael Lustig +5 more
TL;DR: A combination of parallel imaging and compressed sensing is feasible in a clinical setting and may provide higher resolution and/or faster imaging, addressing the challenge of delineating anatomic structures in pediatric MR imaging.
