Nonetheless, breathing-related displacement did not affect mean shear wave speed, which was consistent across all protocols (liver, 1.43 0.07 m/s; kidneys, 2.35 0.21 m/s; spleen, 2.02 0.15 m/s; pancreas, 1.39 0.15 m/s). Image registration before invers …

Spatial heterogeneity of hepatic fibrosis in primary sclerosing cholangitis vs. viral hepatitis assessed by MR elastography.
Reiter R, Shahryari M, Tzschätzsch H, Klatt D, Siegmund B, Hamm B, Braun J, Sack I, Asbach P. Reiter R, et al. Sci Rep. 2021 May 10;11(1):9820. doi: 10.1038/s41598-021-89372-4. Sci Rep. 2021. PMID: 33972639 Free PMC article.
Subjects underwent multifrequency MRE (1.5 T) using drive frequencies of 35-60 Hz and generating shear-wave speed (SWS in m/s) maps as a surrogate of stiffness. The coefficient of variation (CV in %) was determined to quantify fibrosis heterogeneity. Mean SWS and CV were 1 …
