HCC in a patient with chronic hepatitis-C unable to fully cooperate with the recommended breath-holds on the dynamic GRE sequences. Axial DWI b = 50 s/m² (A) and DWI b = 600 s/m² (B), axial pre- (C) and postcontrast fat-suppressed 3D-GRE T1-WI in the arterial (D) and interstitial (E) phases. One nodule on the right hepatic lobe is depicted (arrow, A–E), showing mild high-signal intensity on DWI (A,B). On the dynamic postcontrast images, the lesion shows arterial hyper-enhancement (D), and shows delayed washout and pseudocapsule enhancement (E). Note that the diagnosis of HCC is confident, despite the low quality images due to respiratory motion artifacts (arrowheads, C–E).
