In this study, T1 mapping of a phantom with different
concentration of Polyvinylpyrrolidone (PVP) solutions
and a volunteer were acquired in two different 3T
scanners using DESPOT1 method, and wild bootstrap
analysis was used to assess both intra- and inter-site
uncertainty of quantitative T1 measurements.
