MRI and digital subtraction angiography (DSA) images of a patient receiving early RFA (5 days) after TACE treatment. a–c The lesion (white arrow) showed a rapid increase in signal intensity during the hepatic arterial phase and the portal venous phase; the entire lesion (white arrow) showed rapid washout of the contrast material and became hypointense compared with the surrounding liver parenchyma. Diffusion-weighted imaging (DWI) showed the dispersion constant. d, e DSA images before and after the initial TACE treatment; the tumour staining disappeared (white arrow). f–h One month after combined treatment, the entire lesion (white arrow) showed necrotic foci in the centre, and DWI showed no dispersion constant. i–j After 48 months, there were two lesions in the liver, indicating long-term recurrence (red star sign)
