212 281 Artificial ascites and RFA. A, Intercostal oblique ultrasonogram in the planning stage shows a subtle hypoechoic nodule only on deep inhalation; B, Ultrasonogram in the RFA targeting stage following artificial ascites induction shows the index tumor more clearly, even on shallow breathing. Note the radiofrequency electrode in the index tumor; C, Ultrasonogram taken at the RFA monitoring stage. Note that a hyperechoic RFA zone can be observed.
