目的 探讨磁共振弥散加权成像 (DWI)联合动态增强(DCE-MRI)在肝癌TACE 术后病灶残留评估及随访中的应用价值。 方法 对2015年1月至2016年7月收治的48 肝癌患者进行TACE手术，术后随访3个 月，运用DWI及动态增强进行扫描，并评 价其对残留病灶的检出率。结果 DWI联合 DCE-MRI检测结果的灵敏度、准确度、特 异度显著高于单独运用DWI或DCE-MRI的检 测结果(P<0.05)。结论 DWI联合DCE-MRI 对肝癌TACE术后残留病灶检出率更高，建 议临床广泛推广。

Objective To evaluate the value of magnetic resonance diffusion weighted imaging (DWI) combined with dynamic contrast enhanced (DCE-MRI) in the evaluation and follow-up of residual lesions after liver cancer TACE surgery. Methods TACE surgery was performed on 48 patients with HCC from January 2015 to July 2016. The patients were followed up for 3 months. Detected by DWI or DCE-MRI alone or both of them to evaluate the detection rate of residual lesions. Results The sensitivity, accuracy and specificity of DWI combined with DCE-MRI were significantly higher than those detected by DWI or DCE-MRI alone(P<0.05). Conclusion DWI combined with DCE-MRI has a higher detection rate of residual lesions after TACE for HCC, and it is recommended to be widely popularized.
