[Radiofrequency ablation of rabbit liver: correlation between CT findings and pathological findings].
The purpose of this study was to present the time-related imaging findings and correlative pathological findings of irradiated regions in the rabbit liver. RF ablation was carried out on 16 rabbit livers. Irradiated regions were imaged at 3 days, 4 weeks, and 12 weeks. At 3 days, the regions showed a two-zone structure on plain CT and peripheral enhancement on the arterial phase. The regions presented a three-zone structure on pathological study. At 4 weeks, peripheral enhancement had almost disappeared, and a two-zone structure obscured on plain CT. The CT findings reflected pathological changes after RF ablation.
