磁共振扩散加权成像在宫颈癌诊断和疗效预测中的应用价值

Diagnostic and prognostic value of diffusion weighted imaging in cervical cancer

目的分析磁共振扩散加权成像在宫颈癌诊断和疗效预测中价值。方法60例宫颈癌患者作常规磁共振(MRI)、扩散加权成像(DWI)检查,比较MRI、DWI确诊率及表观扩散系数(ADC)与肿瘤体积、疗效的关系。结果DWI对宫颈癌确诊率较MRI高(P<0.05)。随着肿瘤体积缩小,ADC值显著增加(P<0.05)。ADC值从高到底依次为CR、PR、SD、PD者(P<0.05)。结论DWI明显提高宫颈癌诊断准确率,ADC值可预测治疗效果。

Objective To analyze the diagnostic and prognostic value of diffusion weighted imaging(DWI)in cervical cancer.Methods Sixty patients with cervical cancer underwent conventional magnetic resonance imaging(MRI)and DWI.Diagnostic rate and relationship between apparent diffusion coefficient(ADC)and tumor volume or clinical efficacy were compared between MRI and DWI.Results Diagnostic rate of cervical cancer was higher on DWI than on MRI(P<0.05).ADC value was increased as tumor volume decreased(P<0.05),and changeable from complete response to progression disease in descending order(P<0.05).Conclusion DWI can enhance the diagnostic rate of cervical cancer,and ADC value can predict the therapeutic effect.
