Hemochromatosis (iron overload) occurs in a range of liver diseaes.(1,2) Iron content can be measured invasively with liver biopsy but is commonly replaced by non-invasive MR measurements, including T2* mapping. This is commonly done in a breath-hold to reduce the effects of respiratory motion. In this work we show that a stack of stars radial golden angle T2* mapping multi echo sequence during free breathing in combination with CS reconstruction facilitates high resolution imaging in the liver. This approach bears promise beyond liver imaging for visualizing smaller organs and pathologies, e.g. the pancreas and lymph nodes.
