Robust estimation of quantitative perfusion from multi-phase pseudo-continuous arterial spin labelling

Abstract:
Purpose Multi-phase PCASL has been proposed as a means to achieve accurate perfusion quantification that is robust to imperfect shim in the labelling plane. However, there exists a bias in the estimation process that is a function of noise in the data. In this work, this bias is characterised and then addressed in animal and human data.

Methods The proposed algorithm to overcome bias uses the initial biased voxel-wise estimate of phase tracking ... Expand abstract
