Journal ArticleDOI
Tomoelastography by multifrequency wave number recovery from time-harmonic propagating shear waves
Heiko Tzschätzsch,Jing Guo,Florian Dittmann,Sebastian Hirsch,Eric Barnhill,Korinna Jöhrens,Jürgen Braun,Ingolf Sack +7 more
TL;DR: This work introduces an efficient way of processing wave images acquired by multifrequency magnetic resonance elastography (MMRE), which relies on wave number reconstruction at different harmonic frequencies followed by their amplitude-weighted averaging prior to inversion to reveal variations in tissue elasticity in a tomographic fashion.
Journal ArticleDOI
In vivo wideband multifrequency MR elastography of the human brain and liver.
TL;DR: To demonstrate the feasibility of in vivo wideband MR elastography (wMRE) using continuous, time‐harmonic shear vibrations in the frequency range of 10–50 Hz, high-performance liquid chromatography is used.
Journal ArticleDOI
Tomoelastography of the abdomen: Tissue mechanical properties of the liver, spleen, kidney, and pancreas from single MR elastography scans at different hydration states.
Florian Dittmann,Heiko Tzschätzsch,Sebastian Hirsch,Eric Barnhill,Jürgen Braun,Ingolf Sack,Jing Guo +6 more
TL;DR: To develop a compact magnetic resonance elastography protocol for abdomen and to investigate the effect of water uptake on tissue stiffness in the liver, spleen, kidney, and pancreas.
Journal ArticleDOI
Perfusion alters stiffness of deep gray matter.
Stefan Hetzer,Patric Birr,Andreas Fehlner,Sebastian Hirsch,Florian Dittmann,Eric Barnhill,Jürgen Braun,Ingolf Sack +7 more
TL;DR: The distinct mechano-vascular properties of striatum tissue, as compared to the rest of DGM, may reflect elevated perfusion pressure, which could explain the well-known susceptibility of the putamen to hemorrhages.
Journal ArticleDOI
Tomoelastography of the prostate using multifrequency MR elastography and externally placed pressurized-air drivers.
Florian Dittmann,Rolf Reiter,Jing Guo,Matthias Haas,Patrick Asbach,Thomas Fischer,Jürgen Braun,Ingolf Sack +7 more
TL;DR: To demonstrate the feasibility of in vivo multifrequency magnetic resonance elastography of the prostate using externally placed drivers, a novel MRE technique is developed that combines radiolysis, electrophysiology, and FISH.
