Multi-Field-Strength MRI Brain Atlas Construction in Healthy Chinese Population

21. august 2026 opdateret af: Tang-Du Hospital
This prospective imaging study aims to construct a multi-field-strength magnetic resonance imaging (MRI) brain atlas for healthy Chinese adults. Healthy volunteers will undergo standardized brain MRI examinations at multiple magnetic field strengths, including 0.55T, 1.5T, 3T, 5T, and 7T. Structural, diffusion, functional, and other quantitative MRI data will be acquired and analyzed. The study will characterize the consistency and differences in brain morphology and imaging measurements across field strengths and establish standardized multi-field-strength brain templates and reference data for healthy Chinese adults.

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.
