Synopsis

Spin-lock T1rho is a non-invasive MR imaging method. It has the potentials for the assessment of chronic liver diseases. However, liver iron content can potentially confound T1rho quantification of the liver. In this work, we reported a method to correct the influence of liver iron content on T1rho quantification of the liver at 3.0T.
