Repeated acquisitions of MRI scans of a homogeneous cylindrical phantom are analysed with appropriate statistical techniques to evaluate the variance-covariance matrix of the EPT input. The latter is then propagated through the EPT technique according to the law of propagation of the uncertainty as described in the GUM [Activity A2.3.2].
