Values are mean ± SD. n is number of lesions evaluated in each group. Animals that were going on through the longer follow-up period underwent all examinations planned immediately and at the different intervals until planned sacrifice date. Three minipigs were sacrificed after each follow-up imaging procedure. In 2 pigs (1-mo and 2-mo control groups), only 1 radiofrequency ablation could be performed because of hypoplastic left hepatic lobe.
