摘　　要：目的探讨动态增强磁共振成像(DCE-MRI)结合多b值扩散加权成像(DWI)对宫颈癌病理分期的诊断价值。方法选取65例宫颈癌患者,且经术后病理证实,所有患者均行DCE-MRI、多b值DWI检查,并与术后病理检查结果比较。结果宫颈癌病理分期越高回流速率常数(Kep)、容积转运常数(Ktrans)、容积分数(Ve)参数值越大(P<0.05);DCE-MRI、多b值DWI、DCE-MRI结合多b值诊断符合率分别为89.23%、90.77%、95.38%,差异无统计学意义(P>0.05)。结论DCE-MRI结合多b值DWI可提高宫颈癌病理分期诊断,辅助临床判断病情,具有一定指导意义。Objective To investigate the diagnostic value of dynamic contrast enhanced magnetic resonance imaging(DCE-MRI)combined with multi-b-value diffusion weighted imaging(DWI)in pathological staging of cervical cancer.Methods 65 patients with cervical cancer were selected,and confirmed by pathology after surgery.All patients were subjected to DCE-MRI and multi-b-value DWI,and the examination results were compared with postoperative pathological results.Results The higher the pathological stage of cervical cancer,the larger the reflux rate constant(Kep),the volume transfer constant(Ktrans),and the volume fraction(Ve)(P<0.05).The diagnostic coincidence rates of DCE-MRI,multi-b-value DWI,and DCE-MRI combined with multi-b-value DWI were 89.23%,90.77%,and 95.38%,respectively(P>0.05).Conclusion The combination of DCE-MRI and multi-b-value DWI can improve the pathological staging of cervical cancer and assist clinical judgment of the disease,which indicates certain guiding significance.
