Journal ArticleDOI
Methodological considerations on tract-based spatial statistics (TBSS).
Michael Bach,Frederik Bernd Laun,Alexander Leemans,Chantal M. W. Tax,Geert Jan Biessels,Bram Stieltjes,Klaus H. Maier-Hein +6 more
TL;DR: Specific assumptions of TBSS that may not be satisfied under typical conditions are identified and it is demonstrated that the existence of such violations can severely affect the reliability of T BSS results.
Journal ArticleDOI
Toward an optimal distribution of b values for intravoxel incoherent motion imaging
TL;DR: This work determined optimal b value distributions for the three parameter fit are determined using Monte-Carlo simulations for the measurement of a low, medium and high IVIM perfusion regime.
Journal ArticleDOI
Sodium MRI using a density-adapted 3D radial acquisition technique
Armin M. Nagel,Frederik Bernd Laun,Marc-André Weber,Christian Matthies,Wolfhard Semmler,Lothar R. Schad +5 more
TL;DR: It is shown that the density‐adapted three‐dimensional radial projection reconstruction pulse sequence allows higher resolutions and is more robust in the presence of field inhomogeneities, and benefits for low SNR applications, when compared to conventional three‐ dimensional projection reconstruction sequences.
Journal ArticleDOI
An in vivo verification of the intravoxel incoherent motion effect in diffusion-weighted imaging of the abdomen.
TL;DR: A vascular contribution to the diffusion weighted imaging measurement at low b values is verified and support the Intra Voxel Incoherent Motion‐theory.
Journal ArticleDOI
Differentiation of pancreas carcinoma from healthy pancreatic tissue using multiple b-values: comparison of apparent diffusion coefficient and intravoxel incoherent motion derived parameters.
Andreas Lemke,Frederik Bernd Laun,Miriam Klauss,Thomas J. Re,Dirk Simon,Stefan Delorme,Lothar R. Schad,Bram Stieltjes +7 more
TL;DR: The f value proved to be the best parameter for the differentiation between healthy pancreas and pancreatic cancer using the IVIM-approach, and showed more than a 10-fold higher significance level in distinguishing cancerous from normal tissue when compared with the ADCtot value.
