The Diagnostic Value of Resolve-DWI in Parauterine Infiltration of Cervical Cancer
ObjectiveTo explore the diagnostic value of RESOLVE DWI for paracranial infiltration of cervical cancer.Methods A total of 65 patients with cervical cancer confirmed by surgery and pathology were enrolled,All patients underwent high resolution T2WI,conventional DWI,RESOLVE-DWI examination.The ADC values of DWI images in the two groups were measured,and the ADC values of DWI groups with and without parafunctal infiltration were statistically different.The results of preoperative clinical evaluation and multi-sequence MRI evaluation were compared with the results of surgical pathology.The clinical stages of FIGO,HR-T2WI+conventional DWI,HR-T2WI+RESOLVE-DWI were evaluated.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of the assessment were evaluated.Results three groups were compared with the x2 test of paired data,and the accuracy of the evaluation of uterine invasion was compared between the three groups.Kappa test was used to calculate the consistency of 3 groups of methods to judge the infiltration of uterus and pathological results.Conclusion There was no significant difference in ADC values between the conventional DWI and RESOLVE-DWI groups,and the ADC values in the two groups with paraval infiltration were significantly lower than those in the group without paraval infiltration,and the difference was statistically significant.Compared with FIGO clinical stage,high-HR-T2WI+conventional DWI,HR-T2WI+RESOLVE-DWI can improve the accuracy of the diagnosis of parametrial invasion,and can provide more scientific and reasonable help for the choice oftreatment options for cervical cancer.
