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…
In Vivo Quantification of Glioma-Induced Solid Stress Using MR Elastography and Deformable Image Registration
Noah Jaitner, Mehrgan Shahryari, Jakob Schattenfroh +13
Solid stress is increasingly being recognized as a key driver of tumor progression and aggressiveness, yet it has not been directly measured in patients so far. Here, we combine mu…
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…
