Well-differentiated hepatocellular carcinoma (HCC). Plain T₁-weighted spoiled 2D gradient echo (GRE) A) T₂-weighted half-Fourier acquisition single-shot turbo spin-echo (HASTE) B) hepatocellular phase gadoxetic acid-enhanced fat-suppressed (FS) T₁-weighted spoiled 3D GRE C) and gross pathology D) in the axial plane. A small liver mass in S4b is faintly visible on unenhanced sequences showing characteristics of a HCC nodule such as a rim on T₁-weighted magnetic resonance imaging (MRI) (A). Gadoxetic acid-enhanced MRI shows an enhancing lesion mimicking a benign lesion based on uptake into the well-differentiated HCC confirmed at surgery.
