Liver
fibrosis occurs as a result of long standing chronic liver disease
of various
etiologies. Reversibility
of liver fibrosis has generated considerable attention lately. Early detection of increased liver stiffness would potentially
guide towards more effective treatments. Our accelerated acquisition of
liver tagging MRI to assess liver mechanics allows larger volumetric coverage
and a substantially shorter acquisition time (≈ 80% reduction of total
acquisition) than conventional tagging whilst delivering
comparable results.
