A texture may carry substantial information about the structure of physical objects in medical images, while radiologists usually assess texture only qualitatively as image interpretation. It is important to distinguish early and progressed HCC, since therapeutic strategies are completely different. Theoretically early HCC can remain a little uptake ability of gadoxetic acid, which implies texture analysis of gadoxetic-acid enhanced hepatocyte phase image can be useful for the differentiation between early and progressed HCCs. In this study, we found texture analysis may have additional role for this purpose.
