Size measurements of hepatocellular carcinoma lesions play an important role in treatment algorithms of this disease, however little is known about which MRI sequence has the highest accuracy. This study shows, that there is a significant variance in size assessment of different MRI sequences and phases, while the hepatobiliary-phase seems to be best correlated to histopathologic measurements as the standard of reference and delineates HCC lesions most sharply.
