Image-guided radiofrequency (RF) thermal ablation has been accepted as a promising interventional technique to control unresectable hepatic tumors. One important key to maximize the efficacy of RF ablation is to adhere to the therapeutic guidelines and to avoid preventable pitfalls. There are also several challenges obstructing successful ablation: poor approach path; small sonic window during multiple overlapping ablations; incomplete ablation due to the heat sink effect; subcapsular mass (too exophytic or the mass is adjacent to the gastrointestinal tract); focal residual tumors; too isoechoic or small masses; and mistargeting to adjacent another lesion. Knowledge of these challenges and pitfalls in RF ablation is helpful for a successful ablation.
影像引导下的射频（RF）热消融已被公认为是一种用于控制无法切除的肝肿瘤的有前景的介入技术。使射频消融疗效最大化的一个重要关键是遵循治疗指南并避免可预防的陷阱。还有几个阻碍成功消融的挑战：进针路径不佳；多次重叠消融时声窗小；由于热沉效应导致消融不完全；包膜下肿块（过于外生性或肿块邻近胃肠道）；局灶性残留肿瘤；等回声或小肿块；以及误靶向相邻的另一个病变。了解射频消融中的这些挑战和陷阱有助于成功消融。
