Ristretto MRE: A generalized multi‐shot GRE‐MRE sequence [PDF]

NMR in Biomedicine, 2019
In order to acquire consistent k‐space data in MR elastography, a fixed temporal relationship between the MRI sequence and the underlying period of the wave needs to be ensured. To this end, conventional GRE‐MRE enforces synchronization through repeated triggering of the transducer and forcing the sequence repetition time to be equal to an integer ...

The MRE wrapper approach [PDF]

Proceedings of the 2nd ACM international workshop on Data warehousing and OLAP, 1999
Some of the most recently proposed algorithms for the incremental maintenance of materialized data warehouses (DW), such as SWEEP and PSWEEP, offer several significant advantages over previous solutions, such as high-performance, no potential for infinite waits and reduced remote queries and thus reduced network and information source (IS) loads ...

Comparison of non-invasive assessment of liver fibrosis in patients with alpha1-antitrypsin deficiency using magnetic resonance elastography (MRE), acoustic radiation force impulse (ARFI) Quantification, and 2D-shear wave elastography (2D-SWE)

PLoS ONE, 2018
Purpose Although it has been known for decades that patients with alpha1-antitrypsin deficiency (AATD) have an increased risk of cirrhosis and hepatocellular carcinoma, limited data exist on non-invasive imaging-based methods for assessing liver fibrosis

Magnetic Resonance Elastography of kidneys: SE‐EPI MRE reproducibility and its comparison to GRE MRE

NMR in Biomedicine, 2019
The purpose of this study is 1) to demonstrate reproducibility of spin echo‐echo planar imaging (SE‐EPI) magnetic resonance elastography (MRE) to estimate kidney stiffness; and 2) to compare SE‐EPI MRE and gradient recalled echo (GRE) MRE‐derived stiffness estimations in various anatomical regions of the kidney.Kidney MRE was performed on 33 healthy ...

Linking resource efficiency to environmental sustainability in developing countries [PDF]

Scientific Reports
Material resource efficiency (MRE) is widely recognized as a key strategy for promoting responsible consumption and production. However, the impacts of MRE on environmental sustainability (ES), measured by load capacity factor (LCF), have not been fully ...

A numerical framework for interstitial fluid pressure imaging in poroelastic MRE

PLoS ONE, 2017
A numerical framework for interstitial fluid pressure imaging (IFPI) in biphasic materials is investigated based on three-dimensional nonlinear finite element poroelastic inversion.

Automated liver elasticity calculation for 3D MRE [PDF]

SPIE Proceedings, 2017
Magnetic Resonance Elastography (MRE) is a phase-contrast MRI technique which calculates quantitative stiffness images, called elastograms, by imaging the propagation of acoustic waves in tissues. It is used clinically to diagnose liver fibrosis. Automated analysis of MRE is difficult as the corresponding MRI magnitude images (which contain anatomical ...

Protective Effects of Morus Root Extract (MRE) Against Lipopolysaccharide-Activated RAW264.7 Cells and CCl4-Induced Mouse Hepatic Damage

Cellular Physiology and Biochemistry, 2018
Background/Aims: Inflammation is one of the main contributors to chronic diseases such as cancer. It is of great value to identify the potential activity of various medicinal plants for regulating or blocking uncontrolled chronic inflammation.

Cost-effectiveness of MRE versus VCTE in staging fibrosis for nonalcoholic fatty liver disease (NAFLD) patients with advanced fibrosis

Hepatology, 2023
Introduction: NAFLD is a common cause of liver disease. To determine the optimal testing strategy for NAFLD patients with advanced fibrosis, several factors such as diagnostic accuracy, failure rates, costs of examinations, and potential treatment ...

A wavelet approach of investing behaviors and their effects on risk exposures

Financial Innovation, 2021
Exposure to market risk is a core objective of the Capital Asset Pricing Model (CAPM) with a focus on systematic risk. However, traditional OLS Beta model estimations (Ordinary Least Squares) are plagued with several statistical issues.
