Gradient and shim technologies for ultra high field MRI [PDF]
NeuroImage, 2018 Ultra High Field (UHF) MRI requires improved gradient and shim performance to fully realize the promised gains (SNR as well as spatial, spectral, diffusion resolution) that higher main magnetic fields offer. Both the more challenging UHF environment by itself, as well as the higher currents used in high performance coils, require a deeper understanding

Ultra-high field MRI: looking through the 'macroscope' [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 2013 The first publications about in vivo application of ultra-high field MRI in multiple sclerosis (MS) appeared in 2008. From then on, the number of studies performed at 7 Tesla (T) has rapidly increased. The main advantage of ultra-high field MRI is its higher signal-to-noise ratio, which can be used to increase spatial resolution greatly.
