Hepatic focal lesion after TACE. a T2-WI shows two well-defined HFLs of an intermediate to high signal. b, c DWI and ADC show central areas of true restriction for the smaller lesion (arrow) and heterogeneous restriction for the larger one. d Enhanced T1-WI in the arterial phase shows early arterial heterogeneous enhancement. e Subtracted T1-WI arterial phase shows true enhancement of the lesions (dashed arrows). There is a wedge area of enhancement as well (red arrow). f Enhanced T1-WI in the delayed phase shows washout with capsule enhancement (dashed arrow). The wedge enhancement shows delayed T1-WI persistent enhancement (red arrow). Overall post-treatment assessment is LR-TR viable with post-therapy changes
