Investigation of feasibility and safety of volumetric BH treatment of porcine liver. (A) B-mode ultrasound image guidance during treatment of the liver. The white arrow indicates the location of the hyperechoic region at the focus, which was much less discernible than that in kidney treatments. This is likely due to the aberrating effects of fat-containing body wall overlying the liver. (B) Post-treatment ultrasound evaluation of the treated area. The hypoechoic region of ~1 cm size corresponding to the liquefied area is marked by the two white arrows. As seen, the liquefied region was almost indiscernible in liver and much less defined than that in kidney. This could be due to the aberrating effects of the body wall degrading image quality and/or due to the incomplete loss of structure and retention of the lobular compartments in the ablated area (see below). (C) A representative gross view of the bisected liquefied lesion in the liver. (D) A representative gross view of the body wall overlying the treated liver. The arrow marks what appears to be a mix of mechanical and thermal damage to the fatty layer of the body wall. This collateral damage was observed in three out of the four treated livers.
