We present preliminary quantification of the MR properties of cirrhotic livers using explanted livers. Explanted livers were obtained from the OR and imaged prior to routine pathology processing. T1 and T2* values were quantified using spiral based GRE sequences. T2 was quantified using FSE techniques. Fat was measured using in-phase and out-of-phase GRE images. Good separation between HCC and surrounding cirrhotic tissue using T1 and Fat measures were obtained. T2 showed limited separation between HCC nodules and the cirrhotic tissue. T2* measures were not used due to blurring and distortion in the spiral images when long TE values were used.
