Fast MR signal simulations of microvascular and diffusion contributions using histogram-based approximation and recurrent neural networks. [PDF]

Magn Reson Med
Abstract Purpose Accurate MR signal simulation, including microvascular structures and water diffusion, is crucial for MRI techniques like fMRI BOLD modeling and MR vascular Fingerprinting (MRF), which use susceptibility effects on MR signals for tissue characterization.

"MR Fingerprinting for Imaging Brain Hemodynamics and Oxygenation". [PDF]

J Magn Reson Imaging
ABSTRACT Over the past decade, several studies have explored the potential of magnetic resonance fingerprinting (MRF) for the quantification of brain hemodynamics, oxygenation, and perfusion. Recent advances in simulation models and reconstruction frameworks have also significantly enhanced the accuracy of vascular parameter estimation.

Individual and combined effects of chemical and mechanical power on postoperative pulmonary complications: a secondary analysis of the REPEAT study. [PDF]

Anaesthesia
Summary Introduction Intra‐operative supplemental oxygen and mechanical ventilation expose the lungs to potentially injurious energy. This can be quantified as ‘chemical power’ and ‘mechanical power’, respectively. In this study, we sought to determine if intra‐operative chemical and mechanical power, individually and/or in combination, are associated ...

The Road to a Realistic 3D Model for Estimating R₂ and R₂* Relaxation Versus Gd-DTPA Concentration in Whole Blood and Brain Tumor Vasculature. [PDF]

NMR Biomed
Quantitative DSC perfusion MRI requires knowledge of the relationship between R2(*) relaxation and the concentration of contrast agent. This relationship depends on both physiological and MR parameters, as well as the structure and orientation of the vascular network with respect to the main magnetic field.

Comparison of hygrothermal 2D- and 3D-simulation results with measurements from a test house [PDF]

E3S Web of Conferences, 2020
This article examines whether transient two-dimensional simulations are sufficient or three-dimensional simulations are necessary for the hygrothermal analysis of the three-dimensional detail of a beam support.
