Diffusion pore imaging in the presence of extraporal water
Dominik Ludwig, Frederik Bernd Laun, Karel D. Klika +4
Diffusion-weighted imaging (DWI) is a powerful non-invasive tool which is widely used in clinical routine. Mostly, apparent diffusion coefficient maps are acquired, which cannot be…
NMR diffusion pore imaging: Experimental phase detection by double diffusion encoding
Kerstin Demberg, Frederik Bernd Laun, Johannes Windschuh +3
Diffusion pore imaging is an extension of diffusion-weighted nuclear magnetic resonance imaging enabling the direct measurement of the shape of arbitrarily formed, closed pores by…
Experimental determination of pore shapes using phase retrieval from q-space NMR diffraction
Kerstin Demberg, Frederik Bernd Laun, Marco Bertleff +2
This paper presents a novel approach on solving the phase problem in nuclear magnetic resonance (NMR) diffusion pore imaging, a method, which allows imaging the shape of arbitrary…
On the field strength dependence of bi- and triexponential intravoxel incoherent motion (IVIM) parameters in the liver
Andreas Julian Riexinger, Jan Martin, Susanne Rauh +8
Background: Studies on intravoxel incoherent motion (IVIM) imaging are carried out with different acquisition protocols. Purpose: Investigate the dependence of IVIM parameters on t…
Eddy current compensated double diffusion encoded (DDE) MRI
Lars Mueller, Andreas Wetscherek, Tristan Anselm Kuder +1
Purpose: Eddy currents might lead to image distortions in diffusion weighted echo planar imaging. A method is proposed to reduce their effects on double diffusion encoding (DDE) MR…
Design of a non-linear human breast diffusion coil
Feng Jia, Sebastian Littin, Philipp Amrein +8
Diffusion-weighted imaging (DWI) in the female breast is a magnetic resonance imaging (MRI) technique, which may potentially replace or effectively complement both x-ray mammograph…
Contrast-to-noise ratio analysis of microscopic diffusion anisotropy indices in q-space trajectory imaging
Jan Martin, Sebastian Endt, Andreas Wetscherek +5
Diffusion anisotropy in diffusion tensor imaging (DTI) is commonly quantified with normalized diffusion anisotropy indices (DAIs). Most often, the fractional anisotropy (FA) is use…
Localization regime in diffusion NMR: theory and experiments
Nicolas Moutal, Kerstin Demberg, Denis Grebenkov +1
In this work we investigate the emergence of the localization regime for diffusion in various geometries: inside slabs, inside cylinders and around rods arranged on a square array.…
Retina U-Net: Embarrassingly Simple Exploitation of Segmentation Supervision for Medical Object Detection
Paul F. Jaeger, Simon A. A. Kohl, Sebastian Bickelhaupt +4
The task of localizing and categorizing objects in medical images often remains formulated as a semantic segmentation problem. This approach, however, only indirectly solves the co…
Domain Adaptation for Deviating Acquisition Protocols in CNN-based Lesion Classification on Diffusion-Weighted MR Images
Jennifer Kamphenkel, Paul F. Jaeger, Sebastian Bickelhaupt +8
End-to-end deep learning improves breast cancer classification on diffusion-weighted MR images (DWI) using a convolutional neural network (CNN) architecture. A limitation of CNN as…
Revealing Hidden Potentials of the q-Space Signal in Breast Cancer
Paul Jaeger, Sebastian Bickelhaupt, Frederik Bernd Laun +10
Mammography screening for early detection of breast lesions currently suffers from high amounts of false positive findings, which result in unnecessary invasive biopsies. Diffusion…
NMR-Based Diffusion Lattice Imaging
Frederik Bernd Laun, Tristan Anselm Kuder
Nuclear magnetic resonance (NMR) diffusion experiments are widely employed as they yield information about structures hindering the diffusion process, e.g. about cell membranes. Wh…
Diffusion Pore Imaging by Hyperpolarized Xenon-129 Nuclear Magnetic Resonance
Tristan Anselm Kuder, Peter Bachert, Johannes Windschuh +1
Nuclear magnetic resonance (NMR) diffusion measurements are widely used to derive parameters indirectly related to the microstructure of biological tissues and porous media. Howeve…
Diffusion pore imaging with generalized temporal gradient profiles
Frederik Bernd Laun, Tristan Anselm Kuder
In porous material research, one main interest of nuclear magnetic resonance diffusion (NMR) experiments is the determination of the shape of pores. While it has been a longstandin…
Determination of the Defining Boundary in Nuclear Magnetic Resonance Diffusion Experiments
Frederik Bernd Laun, Tristan Anselm Kuder, Wolfhard Semmler +1
While nuclear magnetic resonance diffusion experiments are widely used to resolve structures confining the diffusion process, it has been elusive whether they can exactly reveal th…
