Fig. 3

Small HCC in the liver of a 48-year-old man treated with MR-guided MWA. Nodules with a diameter of 12 mm are located in the right lobe of the liver. Before MWA, the nodules have a low signal on T1WI (a; dashed circle) and appear with hyperintensity on T2WI (b; dashed circle). Then, MR was used to proform the puncture path in the T1WI sequence and reconfirm it through the T1WI traverse after reaching the tumor target c. After MWA, a typical “target sign” is clearly shown in the ablated area of T1WI d, f, and a low point appears in T2WI immediately after MWA e
