宫颈癌术前分期诊断中CT与MRI的临床应用研究

Study on Clinical Application of CT and MRI in Preoperative Staging Diagnosis of Cervical Cancer

目的:观察分析宫颈癌术前分期诊断中CT与MRI的临床应用。方法:选取2017年2月~2019年6月在本院诊治的50例宫颈癌患者临床资料进行回顾性分析,术前均接受CT及MRI诊断,并接受手术治疗、术后病理分期,比较CT及MRI在宫颈癌术前分期诊断中的应用价值。结果:50例患者病理分期:ⅠA期17例、ⅠB期14例、ⅡA期13例、ⅡB期6例。MRI在ⅠA期、ⅠB中诊断符合率明显高于CT(P<0.05);MRI、CT在ⅡA期、ⅡB期诊断符合率比较无显著差异(P>0.05);肿瘤直径≤3cm诊断中,MRI诊断符合率明显高于CT(P<0.05),肿瘤直径>3cm诊断中,CT、MRI诊断符合率比较无显著差异(P>0.05);以病理诊断为金标准,则CT、MRI联合诊断准确率明显高于单纯CT、MRI诊断(P<0.05)。结论:在宫颈癌术前分期诊断中,MRI在早期、直径≤3cm肿瘤诊断中优势更为显著,通过联合CT与MRI诊断科提高术前分期准确率,为治疗方案的确立提供可靠依据。

Objective:To observe and analyze the clinical application of CT and MRI in the preoperative staging diagnosis of cervical cancer.Methods:The clinical data of 50 patients with cervical cancer in our hospital in the past two years were analyzed retrospectively,all patients were diagnosed by CT and MRI before operation,and received surgical treatment and pathological staging after operation.The application value of CT and MRI in the preoperative staging diagnosis of cervical cancer was compared.Results:The pathological stages of 50 patients were 17 in stageⅠa,14 in stageⅠB,13 in stageⅡA and 6 in stageⅡB.The diagnostic coincidence rate of MRI in stage IA and stage IB was significantly higher than that of CT(P<0.05);there was no significant difference in the diagnostic coincidence rate of MRI and CT in stage IIA and stage IIB(P>0.05);in the diagnosis of tumor diameter≤3cm,the diagnostic coincidence rate of MRI and CT was significantly higher than that of CT(P<0.05);in the diagnosis of tumor diameter>3cm,there was no significant difference in the diagnostic coincidence rate of CT and MRI(P>0.05);if pathological diagnosis was the gold standard,then CT and m were the gold standard The accuracy of RI combined diagnosis was significantly higher than that of CT and MRI alone(P<0.05).Conclusion:In the preoperative staging diagnosis of cervical cancer,MRI has more significant advantages in the early stage and the diameter≤3cm.By combining CT and MRI diagnosis department,the accuracy of preoperative staging can be improved,which provides a reliable basis for the establishment of treatment plan.
