[Application of MRI in the diagnosis of cervical cancer]

Objective: Investigating the diagnostic value of MRI for cervical cancer, including preoperative staging, vagina involvement and lymph node metastasis is the aim of this pape. Methods: Select 116 patients with UCC of the second hospital of JiLin University from October 2016 to April 2019. All patients accept MRI examination. Ultimately, all patients accept surgical treatment. Use SPSS19.0 software to analyze MRI results of all the patients.Using the postoperative pathological results as the golden standard in the diagnosis of cervicalcancer diagnosis. The dates from the MRI preoperative staging, preoperative clinical staging and the postoperative pathologic staging were compared through chi-square test. And the dates of preoperative MRI in cervical cancer vagina involvement and lymph node metastasis diagnosis and postoperative pathological results were compared through Mcnemar chi-square test. The difference was statistically significant(P<0.05). Results: 1, The differences between MRI staging and the postoperative pathologic staging have no statistical significance (P>0.05), whilethe difference between MRI staging and preoperative clinical staging during was statistically significant (P<0.05). Using the postoperative pathological staging as the examination standards, the accuracy of preoperative clinical staging is only 67.5%, and cervical cancer overall preoperative MRI staging accuracy was 95%; 2, Preoperative MRI diagnosis and postoperative pathologic results in cervical vaginal involvement and lymph node metastasis has highsensitivity and specificity, were 97.0%, 96.2%, 93.2%, 97.8%. Checked by Mcnemar chi-square test, the differences between themhave no statisticalsignificance (P>0.05), namely the preoperative MRI diagnosis and postoperative pathological results have consistency in clinical. Conclusion: The combination of MRI and FIGO clinical stage can impro the accuracy of clinical staging of cervical cancer. MRI can be used as the important tool to assess cervical cancer preoperative staging, and to choose and formulate reasonable cervical cancer treatment plan.
