Abstract Functional MRI (fMRI) at 7 T and above provides improved Signal-to-Noise Ratio
and Contrast-to-Noise Ratio compared to 3 T acquisitions. In addition to the beneficial …

Over 20 000 MR systems are currently installed worldwide and, although the majority
operate at magnetic fields of 1.5 T and below (ie about 70%), experience with 3‐T (in high …

In magnetic resonance imaging (MRI), inhomogeneity in the main magnetic field used for
imaging, referred to as off‐resonance, can lead to image artifacts ranging from mild to …

Magnetic resonance imaging (MRI) of the human spinal cord at 7T has been demonstrated
by a handful of research sites worldwide, and the spinal cord remains one of the areas in …

This study aimed to evaluate the ability of BOLD signals at high MRI field (7T) to map fine-
scale single-digit activations in subdivisions (areas 3b and 1) of the human primary …

We report the deployment of spiral acquisition for high-resolution structural imaging at 7T.
Long spiral readouts are rendered manageable by an expanded signal model including …

Background: The clinical course of multiple sclerosis (MS) is mainly attributable to cervical
and upper thoracic spinal cord dysfunction. High-resolution, 7T anatomical imaging of the …

Purpose Applications of dynamic shimming require high field fidelity, and characterizing the
shim field dynamics is therefore necessary. Modeling the system as linear and time …

Over the past few decades, vascular flow-dependent imaging techniques have proven to be
effective for the visualization of large vessel diseases. However, these approaches are …

This work investigates the role of magnetic field fluctuations as a confound in fMRI. In
standard fMRI experiments with single-shot EPI acquisition at 3 Tesla the uniform and …
