The observation of the living body by the magnetic resonance imaging (MRI) depends on the spatial resolution and signal noise ratio (SNR), as well as relaxation time and contrast which is a tissue parameter. The advent of 7 tesla (T) ultra high field MR technology provides unprecedented capabilities for non-invasive imaging of human and animal model brain. This technical ability encompasses a range of functional and structural domains, as well as new opportunities for quantifying neurochemicals using spectroscopic techniques. In addition, increasing the static magnetic field strength promotes signal phase dispersion and shift. Predicted benefits included a stronger Blood Oxygenation Level Dependent (BOLD) effect which is used for detecting brain activity, improved signal and contrast-to-noise (CNR) ratio. By using optimal measurement techniques, improved CNR provides the delineation of the brain microstructure including laminar structure in cortex in vivo. In this talk, I'd like to present our experiences of 7T human brain imaging, especially in high resolution susceptibility imaging and somatotopic fMRI studies.
