1.5T磁共振DWI序列在宫颈癌诊断及临床分期中的价值分析

Value of 1.5T Magnetic Resonance DWI Sequence in the Diagnosis and Clinical Staging of Cervical Cancer

目的分析1.5T磁共振DWI序列在宫颈癌诊断及临床分期中的价值。方法回顾性分析本院2017年1月至2019年5月收治的100例宫颈癌患者的临床资料,观察MRI平扫及增强扫描的影像特点;比较DWI结合常规MRI序列与单纯MRI序列对宫颈癌分期的准确率,以及对宫颈癌盆腔肿大淋巴结检测的检出率。结果 100例宫颈癌患者,常规MRI序列检出90例,10例漏诊,准确率为90.00%;DWI结合常规MRI序列检出97例,3例漏诊,准确率为97.00%。常规MRI序列对宫颈分期准确率与DWI结合常规MRI序列对宫颈癌分期准确率比较P>0.05;DWI结合常规MRI序列对宫颈癌盆腔肿大淋巴结的检出率显著优于单纯常规MRI序列(P<0.05)。结论 MRI检查可有效显示宫颈癌的影像学特点,DWI技术应用于宫颈癌的诊断及临床分期中具有重要的价值,可为临床诊断治疗宫颈癌提供可靠的理论依据。

Objective To analyze the value of 1.5T magnetic resonance DWI sequence in the diagnosis and clinical staging of cervical cancer.Methods The clinical data of 100 patients with cervical cancer admitted to our hospital from January 2017 to May 2019 were retrospectively analyzed.The imaging features of MRI plain scan and enhanced scan were observed.The diagnostic accuracy of DWI combined with conventional MRI sequences or simple MRI sequences for staging of cervical cancer was compared,and detection rate of DWI combined with conventional MRI sequence or simple MRI sequence for enlarged pelvic lymph node of cervical cancer was compared.Results In 100 patients with cervical cancer,90 cases were detected by conventional MRI sequence,10 cases were missed,and the accuracy was 90.00%.97 cases were detected by DWI combined with conventional MRI sequence,and 3 cases were missed and the accuracy was 97.00%.There was no statistically significant difference in the diagnostic accuracy for staging of cervical cancer between conventional MRI sequence and DWI combined with conventional MRI sequence (P>0.05).The detection rate of DWI combined with conventional MRI sequence for enlarged pelvic lymph node of cervical cancer was significantly better than that of simple conventional MRI (P<0.05).Conclusion MRI examination can effectively display the imaging features of cervical cancer.DWI technology has important value in the diagnosis and clinical staging of cervical cancer,and it can provide a reliable theoretical basis for clinical diagnosis and treatment of cervical cancer.
