Building a Liver Perfusion Phantom for Vessel Size Imaging

We have developed a methodology of preparing explant livers for perfusion and vessel size imaging. Off-label use of ferumoxytol is known to provide high quality vessel size maps in vivo; however, known adverse reactions to ferumoxytol may hinder adoption into the clinical workflow. In this case, gadolinium may be more attractive. VSI experiments on a gadolinium perfused liver provide a proof of concept that Gadolinium may be used as an alternative contrast for vessel size imaging.
