abstract = {Magnetic resonance imaging and spectroscopic techniques are
widely used in humans both for clinical diagnostic
applications and in basic research areas such as cognitive
neuroimaging. In recent years, new human MR systems have
become available operating at static magnetic fields of
7 T or higher (≥300 MHz proton frequency). Imaging
human-sized objects at such high frequencies presents
several challenges including non-uniform radiofrequency
fields, enhanced susceptibility artifacts, and higher
radiofrequency energy deposition in the tissue. On the other
side of the scale are gains in signal-to-noise or
contrast-to-noise ratio that allow finer structures to be
visualized and smaller physiological effects to be detected.
This review presents an overview of some of the latest
methodological developments in human ultra-high field
MRI/MRS as well as associated clinical and scientific
applications. Emphasis is given to techniques that
particularly benefit from the changing physical
characteristics at high magnetic fields, including
susceptibility-weighted imaging and phase-contrast
techniques, imaging with X-nuclei, MR spectroscopy, CEST
imaging, as well as functional MRI. In addition, more
general methodological developments such as parallel
transmission and motion correction will be discussed that
are required to leverage the full potential of higher
magnetic fields, and an overview of relevant physiological
considerations of human high magnetic field exposure is
provided.},
