Exploratory scans will be conducted using 7T-MRI to investigate anatomical and functional images for 1 to several times. If necessary, 3T scans will also be conducted. After these scans, image quality will be evaluated using subjective scores by radiologists and other indexes.

Measurement stability of anatomical images were observed using quantitative values. It was relatively low at the skull base, but it was high at the convexity. Age-related changes were different among brain areas and quantitative values as well. MRS could detect more neurochemicals than 3T. Macromolecules are nuisance for quantitation, and they were measured in vivo and analysis parameters were optimized. Analysis method focused on alpha-glucose was also investigated.
