Table 5 The accuracy of liver stiffness estimated by MRE in discrimination between normal and abnormal hepatic tissue in the LLD candidates of the present study (n = 37)

From: Hepatic magnetic resonance elastography: can it be an alternative to invasive biopsy preceding living donor liver transplantation?
