High resolution single-shot EPI at 7T
Magnetic Resonance Materials in Physics, Biology and Medicine, 2007Single-shot echo planar imaging (EPI) acquisitions at 7T are challenging due to increased distortions, signal dropouts, RF-power requirements, and reduced T2*. This study developed and tested pulse sequence and protocol modifications required to allow high resolution EPI for whole brain functional neuroimaging.Using geometric distortion correction ...

About a quarter of human cerebral cortex is tiled with maps of the visual field. These maps can be measured with functional magnetic resonance imaging (fMRI) while subjects view spatially modulated visual stimuli, also known as 'retinotopic mapping'. One of the datasets collected by the Human Connectome Project (HCP) involved ultra-high-field (7 Tesla)

Doppler ultrasound triggering for cardiac MRI at 7T
Magnetic Resonance in Medicine, 2017PurposeA prerequisite for cardiac MR (CMR) imaging is adequate synchronization of image acquisition with the cardiac cycle. Electrocardiogram triggering may be hampered by electromagnetic interferences at high field strength. The purpose of this work is to evaluate the feasibility of Doppler ultrasound triggering for CMR image synchronization at 7T ...

MR Angiography at 7T to Visualize Cerebrovascular Territories
Journal of Neuroimaging, 2016ABSTRACTBACKGROUNDThere is considerable amount of interindividual variability in the size and location of the vascular territories of the major brain arteries. More data are needed to assess the amount of variability and the possible implications for further research and patient care.

Vessel Wall Imaging at 7T: State of the Art
American Journal of NeuroradiologyIntracranial vessel wall imaging (VWI) has emerged as a critical tool in neurovascular diagnostics, enabling direct assessment of the vessel wall, which conventional luminal imaging techniques cannot fully address. While commonly available 3T MRI systems have been valuable for VWI, limitations in spatial resolution and signal-to-noise ratio hinder ...
