Key clinical benefits of neuroimaging at 7T

, 2016
The growing interest in ultra-high field MRI, with more than 35.000 MR examinations already performed at 7T, is related to improved clinical results with regard to morphological as well as functional and metabolic capabilities.

Signal and Contrast Optimization With Predicted Excitations (SCOPE) for Accelerating Large FOV Body Imaging at UHF

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 635-649, August 2026.
ABSTRACT Purpose Large FOV turbo‐spin‐echo (TSE) imaging at ultra‐high field (UHF) remains challenging due to B1+ inhomogeneity and peak specific absorption rate (pSAR) limitations. This work presents a new time‐interleaved acquisition of modes (TIAMO) framework called SCOPE (Signal and Contrast Optimization with Predicted Excitations), which overcomes

What lies beyond 7T

ISMRM
Synopsis  The supralinear gains of signal-to-noise and contrast-to-noise ratios have been a driving force for ultra-high field MRI. Many exciting projects worldwide have emerged to leverage this gain and boost the spatiotemporal resolution of brain images, gain sensitivity in fMRI and increase the spectral peak separation. In this context, the highest

Improved Radiofrequency Safety Modelling in MRI Using In Vivo Measurements of Brain Conductivity

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
A workflow for the comparison of simulated and measured B1+$$ {B}_1^{+} $$ maps was developed and applied to a study on human tissue (brain) electrical conductivity, investigating differences between conductivity values from ex vivo and in vivo measurements.

Clinical vascular imaging in the brain at 7T

, 2016
Stroke and related cerebrovascular diseases are a major cause of mortality and disability. Even at standard-field-strengths (1.5T), MRI is by far the most sensitive imaging technique to detect acute brain infarctions and to characterize incidental ...

Automated hippocampal subfield segmentation at 7T MRI [PDF]

, 2016
BACKGROUND AND PURPOSE: High resolution 7T MRI is increasingly used to investigate hippocampal subfields in vivo, but most studies rely on manual segmentation which is labor intensive.

Resting State Networks in the TgF344-AD Rat Model of Alzheimer’s Disease Are Altered From Early Stages

Frontiers in Aging Neuroscience, 2019
A better and non-invasive characterization of the preclinical phases of Alzheimer’s disease (AD) is important to advance its diagnosis and obtain more effective benefits from potential treatments.
