Convergent imaging-transcriptomic evidence for disturbed iron homeostasis in Gilles de la Tourette syndrome Open
Gilles de la Tourette syndrome (GTS) is a neuropsychiatric movement disorder with reported abnormalities in various neurotransmitter systems. Considering the integral role of iron in neurotransmitter synthesis and transport, it is hypothes…

High Angular Resolution Susceptibility Imaging and Estimation of Fiber Orientation Distribution Functions in Primate Brain Open
Uncovering brain-tissue microstructure including axonal characteristics is a major neuroimaging research focus. Within this scope, anisotropic properties of magnetic susceptibility in white matter have been successfully employed to estimat…

Multi-Echo Investigations of Positive and Negative CBF and Concomitant BOLD Changes Open
Unlike the positive blood oxygenation level-dependent (BOLD) response (PBR), commonly taken as an indication of an ‘activated’ brain region, the physiological origin of negative BOLD signal changes (i.e. a negative BOLD response, NBR), als…

Deconvolution‐based distortion correction of EPI using analytic single‐voxel point‐spread functions Open
Purpose To develop a postprocessing algorithm that corrects geometric distortions due to spatial variations of the static magnetic field amplitude, B 0 , and effects from relaxation during signal acquisition in EPI. Theory and Methods An a…

Modular 3D-printable resolution phantom for magnetic resonance imaging Open
Modular CAD model (STL format) for 3D-printing of a resolution phantom for magnetic resonance imaging (MRI). The cylindrical phantom (inner diameter 154 mm, height 44 mm) contains a central cuboid (140 mm x 30 mm x 17 mm) with diagonally o…

Increased Sensitivity and Signal-to-Noise Ratio in Diffusion-Weighted MRI using Multi-Echo Acquisitions Open
Post-mortem diffusion MRI (dMRI) enables acquisitions of structural imaging data with otherwise unreachable resolutions - at the expense of longer scanning times. These data are typically acquired using highly segmented image acquisition s…

Three-dimensional echo-planar cine imaging of cerebral blood supply using arterial spin labeling Open
The EPICYCLE technique was successfully applied to track a short bolus of labeled arterial blood during its passage through the cerebral vasculature.
