Institute of Neuroradiology - Department Advanced MRI
Microstructure MRI Group
The Microstructure MRI Group focuses on developing reproducible and robust MR physics methods, advancing quantitative MRI, and validating in vivo histology using MRI (hMRI). Our MR Physics group is part of the Institute of Neuroradiology, UKSH-Lübeck. We are based at both the University of Lübeck and the University Medical Center Hamburg-Eppendorf (UKE).
Overview
Understanding basic mechanisms underlying normal and diseased human brain developments crucially depends on reliable knowledge of its anatomical microstructure and connectivity. Our long-term goal is to estimate microstructural properties non-invasively in living subjects using biophysical models of the MRI signal.
We are developing novel methods for fusion of high-resolution quantitative MRI (qMRI) to enable MRI-based in vivo histology (hMRI) in the brain and spinal cord. The main focus is to develop valid MRI metrics that characterize key white matter microstructure properties as known from ex vivo histology (e.g. myelin density, fiber density, and the g-ratio i.e. the ratio between inner and outer fiber diameter).
