磁共振弥散加权成像联合动态增强在评估肝癌TACE术后病灶残留及随访中的应用价值

The Value of Magnetic Resonance Diffusion Weighted Imaging Combined with Dynamic Enhancement in Assessing Lesion Residual and Follow-up after TACE

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.
