Journal ArticleDOI
A comparative simulation study of bayesian fitting approaches to intravoxel incoherent motion modeling in diffusion-weighted MRI.
TL;DR: To assess the performance of various least squares and Bayesian modeling approaches to parameter estimation in intravoxel incoherent motion (IVIM) modeling of diffusion‐weighted MRI data, a large number of models were used.
Journal ArticleDOI
Minimax current density gradient coils: analysis of coil performance and heating
TL;DR: This method is shown to be able to increase coil efficiency when constrained by minimum wire spacing rather than switching times or total power dissipation, which could be used to increase gradient strength, duty cycle, or buildability.

TL;DR: In this paper, a substantially improved version, IVIM-NEToptim, was presented, and characterizes its superior performance in pancreatic cancer patients, compared to least squares (LS) and a Bayesian approach at different SNRs.
Journal ArticleDOI
Magnetic Lenz lenses improve the limit-of-detection in nuclear magnetic resonance
Nils Spengler,Peter T. While,Markus Meissner,Markus Meissner,Ulrike Wallrabe,Jan G. Korvink,Jan G. Korvink +6 more
TL;DR: For the first time, the use of Lenz lenses are presented to focus the magnetic flux of an RF coil into a smaller volume and thereby locally enhance the sensitivity of the NMR experiment—at the expense of the total sensitive volume.
