The Physics of Magnetic Resonance Imaging MRI is an imaging modality reliant on the nuclear resonance properties of tissues Every atom has a nuclear magnetic spin, an inherent property of atoms (as a consequence of it being a property of fundamental particles), which dictates its rotation about an axis through its centre These magnetic spins Recently, ultrahighfield (static magnetic field ≥ 7T) MRI has attracted increasing attention because it can provide higher signaltonoise7T MRI research in neurology initial results and future research applications The CJ Gorter Center for High Field Magnetic Resonance Imaging (MRI) at the Leiden University Medical Center was established within the Department of Radiology in late 07 The aim of the center is the development of new

The progression to 7 Tesla (7 T) magnetic resonance imaging (MRI) yields promises of substantial increase in signaltonoise (SNR) ratio This increase can be traded off to increase image spatial resolution or to decrease acquisition time However, renal 7 T MRI remains challenging due to inhomogeneity of the radiofrequency field and due toThe Magentom Terra is the first 7T MRI system cleared for clinical use in the United States The spatial resolution of 7T MRI approaches the scale of pathologies of interest in degenerative brain diseases, such as amyloid plaques and changes in cortical layers and subcortical nuclei It may reveal new information about neurodegenerative dementias, although challenges may include increased artefact production and more adverse effects We performed a systematic
