Ultra-wideband MRE of the human liver and spleen for viscoelastic model identification in hepatic inflammation
Jakob Schattenfroh, Michael Fedders, Steffen P. Häseli +10
Magnetic resonance elastography (MRE) is established for noninvasive assessment of liver fibrosis. Conventional abdominal MRE is typically limited to 40-60 Hz. Lower frequencies re…
ARGUS: Accelerated, Robust, General, and Unsupervised Cell Tracking Solutions
Noah Jaitner, Kandice Tanner, Ingolf Sack +1
Background and Objective: Quantitative analysis of cell dynamics is central to modern biological research, providing critical insights into immune cell interactions, disease progre…
ILPU: Iterative Laplace-Based Phase Unwrapping via Bi-Level Optimization
Michael Fedders, Jakob Schattenfroh, Yanglei Wu +6
Phase unwrapping is an essential preprocessing step for phase-based MRI applications, including susceptibility mapping, field mapping, thermometry, and MR elastography. We present…
In Vivo Wideband MR Elastography for Assessing Age-Related Viscoelastic Changes of the Human Brain
Jakob Schattenfroh, Tom Meyer, Hossein S. Aghamiry +10
Magnetic Resonance Elastography (MRE) noninvasively maps brain biomechanics and is highly sensitive to alterations associated with aging and neurodegenerative disease. Most impleme…
Technical recommendation on multiplex MR elastography for tomographic mapping of abdominal stiffness with a focus on the pancreas and pancreatic ductal adenocarcinoma
Jakob Schattenfroh, Salma Almutawakel, Jan Bieling +21
Objectives: MR elastography (MRE) offers valuable mechanical tissue characterization, however, in deep abdominal organs like the pancreas conventional single-driver, single-frequen…
