Denoising High-Field Multi-Dimensional MRI With Local Complex PCA

Frontiers in Neuroscience, 2019
Modern high field and ultra high field magnetic resonance imaging (MRI) experiments routinely collect multi-dimensional data with high spatial resolution, whether multi-parametric structural, diffusion or functional MRI.

Inconsistencies in atlas-based volumetric measures of the human nucleus basalis of Meynert: A need for high-resolution alternatives

NeuroImage, 2022
The nucleus basalis of Meynert (nbM) is the major source of cortical acetylcholine (ACh) and has been related to cognitive processes and to neurological disorders. However, spatially delineating the human nbM in MRI studies remains challenging.

Feasibility of using ultra-high field (7 T) MRI for clinical surgical targeting. [PDF]

PLoS ONE, 2012
The advantages of ultra-high magnetic field (7 Tesla) MRI for basic science research and neuroscience applications have proven invaluable. Structural and functional MR images of the human brain acquired at 7 T exhibit rich information content with ...

The TRACK-PD study: protocol of a longitudinal ultra-high field imaging study in Parkinson’s disease

BMC Neurology, 2020
Background The diagnosis of Parkinson’s Disease (PD) remains a challenge and is currently based on the assessment of clinical symptoms. PD is also a heterogeneous disease with great variability in symptoms, disease course, and response to therapy.

Ultra-high field cardiac MRI in large animals and humans for translational cardiovascular research

Frontiers in Cardiovascular Medicine, 2023
A key step in translational cardiovascular research is the use of large animal models to better understand normal and abnormal physiology, to test drugs or interventions, or to perform studies which would be considered unethical in human subjects ...

Low-Field MRI: How Low Can We Go? A Fresh View on an Old Debate

Frontiers in Physics, 2020
For about 30 years, MRI set cruising speed at 1.5 T of magnetic field, with a gentle transition toward 3 T systems. In its first 10 years of existence, there was an open debate on the question of most relevant MRI field strengths considering the gain in ...

Enhancement of transmit and receive efficiencies with hybridized meta-atom in 7T head coil array

, 2019
International audienceB1 + heterogeneity remains an important challenge for ultra-high field MRI scanners (B0≥7T). There are two methods to mitigate this problem: parallel transmission pTx [1], and passive shimming using high-dielectric pads [2], in this
