Model-based image reconstruction with wavelet sparsity regularization for through-plane resolution restoration in Tsub2/sub-weighted spin-echo prostate MRI

Autor: Eric A, Borisch, Adam T, Froemming, Roger C, Grimm, Akira, Kawashima, Joshua D, Trzasko, Stephen J, Riederer

Publikováno v: Magnetic resonance in medicine. 89(1)

The purpose is to develop a model-based image-reconstruction method using wavelet sparsity regularization for maintaining restoration of through-plane resolution but with improved retention of SNR versus linear reconstruction using Tikhonov (TK) regu

Cross correlation–based misregistration correction for super resolution T 2 ‐weighted spin‐echo images: application to prostate

Autor: Eric A. Borisch, Akira Kawashima, Soudabeh Kargar, Stephen J. Riederer, Phillip J. Rossman, Roger C. Grimm

Publikováno v: Magnetic Resonance in Medicine. 85:1350-1363

Purpose The purpose is to develop a retrospective correction for subtle slice-to-slice positional inconsistencies that can occur when overlapped slices are acquired for super resolution in T2 -weighted spin-echo multislice imaging. Methods Spin-echo

Modified acquisition strategy for reduced motion artifact in super resolution FSE multislice MRI: Application to prostate

Autor: Stephen J. Riederer, Bernard F. King, Roger C. Grimm, Adam T. Froemming, Akira Kawashima, Eric G. Stinson, Soudabeh Kargar, Eric A. Borisch

Publikováno v: Magnetic Resonance in Medicine. 84:2537-2550

Purpose To reduce slice-to-slice motion effects in multislice T 2 -weighted fast-spin-echo ( T 2 FSE) imaging, manifest as "scalloping" in reformats, by modification of the acquisition strategy and to show applicability in prostate MRI. Methods T 2 F

Time‐resolved contrast‐enhanced MR angiography with single‐echo Dixon fat suppression

Autor: Norbert G. Campeau, John Huston, Joshua D. Trzasko, James F. Glockner, Stephen J. Riederer, Phillip M. Young, Eric G. Stinson

Publikováno v: Magnetic Resonance in Medicine. 80:1556-1567

Purpose Dixon-based fat suppression has recently gained interest for dynamic contrast-enhanced MRI, but multi-echo techniques require longer scan times and reduce temporal resolution compared to single-echo alternatives without fat suppression. The p
