Magn Reson Med
. 2022 Sep;
89(1):454-468.
PMID: 36093998
Purpose: 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...

Jiang K, Ferguson C, Grimm R, Zhu X, Glockner J, Lerman L
Invest Radiol
. 2021 Dec;
57(5):334-342.
PMID: 34935650
Objectives: Quantitative magnetization transfer (qMT) is useful for measurement of murine renal fibrosis at high and ultrahigh field strengths. However, its utility at clinical field strengths and in human-like kidneys...

Borisch E, Grimm R, Kargar S, Kawashima A, Rossman P, Riederer S
Magn Reson Med
. 2020 Sep;
85(3):1350-1363.
PMID: 32970892
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 T -weighted spin-echo multislice...

Kargar S, Borisch E, Froemming A, Grimm R, Kawashima A, King B, et al.
Magn Reson Med
. 2020 May;
84(5):2537-2550.
PMID: 32419197
Purpose: To reduce slice-to-slice motion effects in multislice -weighted fast-spin-echo ( FSE) imaging, manifest as "scalloping" in reformats, by modification of the acquisition strategy and to show applicability in prostate...

Magn Reson Med
. 2019 Mar;
81(6):3691-3704.
PMID: 30844092
Purpose: The goal of this work is to demonstrate 1 mm through-plane resolution in multislice T2SE MRI using k -space processing of overlapping slices and show applicability in prostate MRI....

47(4):976-987.
PMID: 28801939
Purpose: To assess the success rate, image quality, and the ability to stage liver fibrosis of a standard 2D gradient-recalled echo (GRE) and four different spin-echo (SE) magnetic resonance elastography...

Magn Reson Imaging
. 2017 Jan;
39:15-23.
PMID: 28132859
Purpose: To assess whether acquisition with 32 receiver coils rather than the vendor-recommended 12 coils provides significantly improved performance in 3D dynamic contrast-enhanced MRI (DCE-MRI) of the prostate. Materials: The...
