肺肿瘤CT引导下经皮射频消融后的影像评估进展

The advance of imaging evaluation after CT-guided percutaneous radiofrequency ablation for lung tumors

近年来,CT引导下经皮射频消融术在无法手术切除或转移性肺肿瘤的治疗中备受推崇。但因术后病理改变的复杂性,不同影像检查的表现既存在重叠,又存有差异,使得评估充满挑战。就不同影像方法(CT、PET/CT、MRI)对肺肿瘤病人术后不同时期的评估进展予以综述,以期更好地指导临床。

CT-guided percutaneous radiofrequency ablation （RFA） has been adopted to treat primary unresectable lung tumors and metastatic lung tumors, recently. However, evaluation after RFA is always challenging because of the overlap and difference in imaging manifestations under certain modalities based on the complexity of post-surgical pathology. We reviewed the advance of various medical imaging methods （CT,PET/CT,MRI） in evaluating patients with lung tumors after RFA with purpose of suitable selection of modality in evaluation.
