Biomechanical Modeling of Cortical Layers

Bio-physical modelling

We characterize the cortical layers by biomechanical modeling and simulation of the developed human cortex tissue in-vivo using hyperelastic material models.

Quantification of transverse relaxation times of human cortical and subcortical structures in vivo at 7T

Bio-physical modelling Image-processing MR-physics Validation and Application

Transverse relaxation parameters are quantified in vivo for different cortical structures of the human brain at ultra-high field strength.

Relating layer-specific quantitative 7T MRI to histology, gene expression and connectomics

Neuroanatomy Validation and Application

We investigate the relationship between quantitative MRI (qMRI) at different cortical depths and cell counts, gene expression and white matter connections in the brain in order to provide novel biomarkers for tracking neurodegenerative diseases.

A multi-modal approach to in vivo U-fibre mapping in the early visual processing stream

Neuroanatomy Validation and Application

Robust U-fibre connectivity mapping can be achieved in vivo in the early visual processing stream using combined diffusion weighted imaging and functional retinotopy

Cortical myelination in chimpanzees

Neuroanatomy Validation and Application

In this project, we investigate the brains of wild chimpanzees who died of natural causes at different developmental stages using high-resolution quantitative MRI and histology.

Image detail: Activation maps acquired with and without an MT-pulse

First Experience with Arterial Blood Contrast (ABC) fMRI in the Human Motor Cortex at 7 Tesla

MR-physics Validation and Application

Using a field strength of 7 Tesla, the "Arterial Blood Contrast" (ABC), which is based on the Magnetization Transfer effect, could be measured with an isotropic spatial resolution of 1.5 mm in combination with a conventional functional MRI contrast.

Evaluating different k-space undersampling schemes with iterative and deep learning image reconstruction for fast multi-parameter mapping (MPM)

Image-processing MR-physics

DeepcomplexMRI deep learnig reconstruction has been modified to process multi-echo MRI images. First results for different undersampling strategies suggest that performance is comparable to modern iterative algorithms like ENLIVE while taking only about 5 minutes to reconstruct a full 3D 1mm³/voxel resolved head image stack.

Parallel transmit kT-points pulses for improving high resolution quantitative multi-parameter mapping (MPM)

MR-physics

We implemented and optimized kt-points RF pulses to reduce bias and shading artifacts in whole brain ultra-high resolution MPM.

Examination of draining vein contributions in GE- and SE-EPI BOLD across cortical depth at 7 T

MR-physics Validation and Application

In this project, we study the resolution limits of different high-resolution functional magnetic resonance imaging (fMRI) methods to resolve differences within the cerebral cortex.

Mapping ocular dominance columns in humans using GE-EPI, SE-EPI and SS-SI VASO at 7 T

MR-physics Validation and Application

Multi-Parameter Mapping for the NISCI Multi-Center Clinical Trial

Image-processing MR-physics Validation and Application

Embedded in the clinical trial NISCI (Nogo inhibition in spinal cord injury: www.nisci-2020.eu), we employ whole brain quantitative imaging at 3 Tesla as a new biomarker for de- and regeneration.

fMRI of the Basal Ganglia at 7T using single- and multi-echo protocols

MR-physics

In order to study the Basal Ganglia in relation to cortical areas, the used fMRI protocol has to be carefully adjusted with respect to its region of interest and the necessary signal under-sampling. We performed a study at a field strength of 7 Tesla investigating the dependence of the detected signal on the MR parameters employed.
