Detaljeret beskrivelse
This is a prospective multi-field-strength neuroimaging study involving healthy Chinese adults. Eligible participants will undergo standardized brain MRI examinations at 0.55T, 1.5T, 3T, 5T, and 7T according to the study protocol.
MRI acquisitions include structural imaging, diffusion imaging, functional imaging, and quantitative imaging sequences where applicable. Images will undergo standardized preprocessing, registration, segmentation, and quantitative analysis. Multi-field-strength brain templates will be constructed, and anatomical and functional imaging characteristics will be compared across magnetic field strengths.
The study aims to establish normative multi-field-strength MRI reference data and brain atlases for healthy Chinese adults and to evaluate the consistency and field-strength-related differences in brain morphometry, cortical measurements, diffusion characteristics, functional connectivity, and other quantitative MRI parameters.
