射频消融已成为治疗肝癌的公认的有效方法;CT以其突出优势成为射频消融术后疗效评价的重要影像学手段。正确认识射频消融灶在不同阶段的形态学及功能学改变,有助于及时准确发现局部残留或复发,实行有效干预,改善患者预后。本研究就CT增强扫描及灌注成像在肝癌射频消融术后疗效评价方面的研究进展进行综述。
Radiofrequency ablation (RFA) has become a recognized effective method for the treatment of liver cancer. CT has become an important imaging method for the evaluation of the curative effect after radiofrequency ablation with its outstanding advantages. Correct understanding of radio frequency ablation in different stages of morphological and functional changes, help to find the local residue or recurrence in time accurately, the implementation of effective intervention to improve patient prognosis. This review summarizes the progress of CT-enhanced scanning and perfusion imaging in the evaluation of curative effect of radiofrequency ablation of liver cancer.
