摘　　要：目的:探讨磁共振弥散加权成像(DWI)和CT增强扫描在宫颈癌诊断中的效能。方法:选取2021年1月—2024年8月滨州市中心医院收治的167例疑似宫颈癌患者纳入研究,研究对象均接受DWI和CT增强扫描检查,并以病理检查结果为“金标准”,使用Kappa值衡量二者单独及联合诊断与“金标准”结果的一致性,评估二者单独及联合诊断宫颈癌的效能,并比较宫颈良恶性病变的DWI参数差异。结果:CT增强扫描与病理检查的一致性中等(Kappa=0.695,P=0.012),DWI与病理检查的一致性中等(Kappa=0.663,P=0.009),联合检查与病理检查的一致性较好(Kappa=0.773,P=0.002)。联合检查的灵敏度、准确度、阳性预测值、阴性预测值大于CT增强扫描和DWI单独检查(P<0.05);三种检查方式特异度比较,无统计学差异(P>0.05)。宫颈恶性病变者的流入率、流出率及表观扩散系数高于宫颈良性病变者,达峰时间低于宫颈良性病变者(P<0.001)。结论:DWI和CT增强扫描联合使用诊断宫颈癌的效能更高,DWI参数在宫颈良恶性病变的鉴别诊断中具有一定的参考价值。Objective:To investigate the efficacy of diffusion-weighted magnetic resonance imaging(DWI)and CT-enhanced scanning in the diagnosis of cervical cancer.Methods:A total of 167 patients with suspected cervical cancer admitted to Binzhou Central Hospital from January 2021 to August 2024 were enrolled in this study.All subjects underwent DWI and CT-enhanced scanning,with pathological examination results serving as the"gold standard".The Kappa value was used to measure the consistency of the results of single and combined diagnoses of DWI and CT scanning with the"gold standard".The efficacy of single and combined diagnoses of CT scanning and DWI in the diagnosis of cervical cancer was evaluated,and the differences in DWI parameters between benign and malignant cervical lesions were compared.Results:The consistency of CT-enhanced scanning and pathological examination was moderate(Kappa=0.695,P=0.012),the consistency of DWI and pathological examination was moderate(Kappa=0.663,P=0.009),and the consistency of combined examination and pathological examination was good(Kappa=0.773,P=0.002).The sensitivity,accuracy,positive predictive value,and negative predictive value of the combined examination were higher than those of CT-enhanced scanning and DWI alone(P<0.05).There was no significant difference in the specificity of the three methods(P>0.05).The inflow rate,outflow rate,and apparent diffusion coefficient of patients with malignant cervical lesions were higher than those with benign cervical lesions,and the time to peak was lower than those with benign cervical lesions(P<0.001).Conclusion:The combined use of DWI and CT-enhanced scanning is more effective in the diagnosis of cervical cancer,and DWI parameters have a certain reference value in the differential diagnosis of benign and malignant cervical lesions.
