Fig. 6: Coagulation of the needle track

Fig. 7: For larger tumors, multiple ablations were needed to be overlapped to build a composite thermal lesion with sufficient size to
kill the entire tumor and to provide 0.5-1 cm tumor-free margin

Fig. 8: The deepest ablations were performed before the superficial ones to minimize the possibility of microbubbles that might obscure
visualization of the deepest portions of the tumor

especially if there has been any contact with the tumor, tumor and thus prevent completion of the ablation (Fig. 8). In
(Fig. 7). The deepest ablations were performed before the case of tumours bulging on liver surface, the hilar portion of the
superficial ones to minimize the possibility of microbubbles tumor was ablated initially in order to destroy the inflow of
that might obscure visualization of the deepest portions of the blood supplying the tumor (Fig. 9).
