Comparison of breath-hold, respiratory navigated and free-breathing MR elastography of the liver

IG Murphy, Martin Graves, S Reid, Andrew James Patterson, I Patterson, AN Priest & David Lomas
$\textit{Purpose:}$ Hepatic magnetic resonance elastography (MRE) is currently a breath-hold imaging technique. Patients with chronic liver disease can have comorbidities that limit their ability to breath-hold (BH) for the required acquisition time. Our aim was to evaluate whether stiffness measurements obtained from a navigator-triggered MRE acquisition are comparable to standard expiratory breath-hold, inspiratory breath-hold or free-breathing in healthy participants. $\textit{Materials and methods:}$ Twelve healthy participants were imaged using the four methods on a clinical 1.5...
