摘　　要：目的探讨磁共振成像对原发性肝癌射频消融术后疗效的评估价值。方法选取46例行射频消融术的原发性肝癌患者术前及术后3个月进行肝脏MRI平扫、DWI及增强检查,分析术后疗效。结果46例原发性肝细胞癌患者57个病灶,术后3个月时所有病灶均较术前缩小,无肿瘤残留者47个病灶,MRI表现T2WI压脂像呈低信号,DWI信号减低,ADC呈高信号,肿瘤复发者10个病灶,MRI表现T2WI压脂像仍呈高信号,DWI呈高信号,ADC呈低信号。结论MRI能够评估肝癌射频消融术后肿瘤是否残存或复发,及早检出复发灶,对制定下一步治疗方案意义重大。Objective To explore the value of magnetic resonance imaging in evaluating the efficacy of radiofrequency ablation for primary liver cancer.Methods 46 patients with primary liver cancer undergoing radiofrequency ablation were enrolled.All patients received DWI and enhancement examnation before and 3 months after operation.Results There were 57 lesions in 46 patients with primary hepatocellular carcinoma.After 3 months,all the lesions were smaller than those before operation.There were 47 lesions without tumor residue.MRI showed low signal on T2WI,the ADC value post-ablation increased.10 lesions with tumor recurrence showed high signal on T2WI and DWI.Conclusion MRI has the capacity in evaluating the effect of radiofrequency ablation in liver cancer.
