  • Short Description
    • Structural MRI data from 5 healthy volunteers scanned multiple times on multiple sites having different 1.5T systems (Siemens, GE, Piker). For each subject, four multi-spectral structural scans were obtained in a single scan session, from which tissue proton density and T1 maps can be derived. These data was acquired to investigate various metrics of within-site and across-site reproducibility.
