摘要
目的分析磁共振扩散加权成像(DWI)、MR动态增强扫描在宫颈癌诊断中的临床价值。方法选取云浮市人民医院2016年1月至2018年12月明确诊断为宫颈癌患者70例,均行DWI及MR动态增强扫描检查,病理结果为金标准,选取同期健康体检女性70例作为对照组。分析DWI、MR动态增强扫描联合检测对宫颈癌的诊断价值,比较两组间扩散系数(ADC)、转运系数(K^(trans))、速率常数(Kep)、容积分数(Ve)水平。结果DWI、MR动态增强扫描联合检查诊断宫颈癌的灵敏度、特异度、准确度均高于单一检查,差异有统计学意义(P<0.05);宫颈癌组ADC水平低于对照组,K^(trans)、Kep水平高于对照组(P<0.05),两组间Ve水平比较差异无统计学意义(P>0.05)。结论DWI、MR动态增强扫描联合检查对宫颈癌的诊断效能高于单一DWI、MR动态增强扫描。
Objective To analyze the clinical value of diffusion weighted imaging(DWI)combined with dynamic contrast-enhanced MRI(DCE-MRI)in the diagnosis of cervical cancer.Methods A total of 70 patients with cervical cancer who were definitely diagnosed in Yunfu People’s Hospital from January 2016 to December 2018 were selected as the cervical cancer group(n=70)and examined by DWI and DCE-MRI,and the pathological results were the gold standard.Women who had physical examination in the same period were selected as the control group(n=70).The diagnostic value of DWI and DCE-MRI in cervical cancer was analyzed,and the apparent diffusion coefficient(ADC),transport coefficient(K^(trans)),rate constant(Kep)and volume fraction(Ve)between the two groups were compared.Results The sensitivity,specificity and accuracy of DWI and DCE-MRI in the diagnosis of cervical cancer were higher than those of single examination,with statistically significant difference(P<0.05).ADC level in the cervical cancer group was lower than that in the control group,while K^(trans)and Kep levels were higher than those in the control group(P<0.05),and there was no significant difference in Ve level between the two groups(P>0.05).Conclusion The diagnostic efficiency of DWI combined with DCE-MRI in cervical cancer is higher than that of DWI and DCE-MRI alone.
