Figures & data
Figure 1. (a) Preablation contrast enhanced MRI demonstrates an arterially enhancing HCC. The liver capsule adjacent to the HCC is 3 mm from the adjacent colon. (b) Intraablation noncontrast CT performed after hydrodisplacement demonstrates that the colon has moved, now 16 mm from the liver capsule. The fluid thickness in this case is 13 mm. Notice also the two microwave antennae which have been placed.
Figure 2. (a) Preablation contrast enhanced CT demonstrates an arterially enhancing right lobe HCC. The overlying liver capsule directly abuts the body wall, putting this patient at risk for postprocedural pain. (b) Postablation contrast enhanced CT demonstrates postablation changes as well as instillation of artificial ascites, measuring 15 mm in thickness between the body wall and the liver capsule. (c) Postablation contrast enhanced CT demonstrates the artificial ascites needle still in place, allowing for continuous instillation of fluid during the ablation procedure.
