MR imaging of male patient 2 m after combined microwave and TACE for multifocal right lobe HCC. A–C Axial T2 seq. reveals coagulative necrosis within central portion of ablated lesion and peripheral hyperinensity at segments VIII and VII focal lesions. D–I Diffusion MR study and ADC map reveals areas of restricted diffusion at periphery of segments VIII and VII (ADC value = 0.8) as well as free diffusion of segment V/VI focal lesion. J & K Dynamic contrast-enhanced MR study and subtraction reveal no contrast enhancement of segment V/VI focal lesion at arterial or portal phases as well as areas of arterial and portal enhancement at periphery of segments VIII and VII focal lesions with delayed washout denoting viable tumor tissue
