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.
