MR Imaging of Hepatocellular Adenomas and Differential Diagnosis Dilemma

Figure 9

HCC in noncirrhotic liver. (a) Axial T2w image. In S II-S III slightly hyperintense well delineated lesion (arrow). (b-c) In T1w in- and out-phased images of the lesion appears hypointense. (d–h) In dynamic evaluation after Gd-EOB-DTPA administration the nodule appears slightly hypervascular in arterial phase (e); it shows rapid and progressive wash out in portal and equilibrium phases. Note the presence of a pseudocapsule (arrowhead) in equilibrium phase. (i) Hepatobiliary phase image after 20′. The lesion appears hypointense. (j) Pathologic specimen confirms the presence of HCC nodule in normal liver.
