Abstract:
Objective:To explore application value of magnetic resonance imaging(MRI)combined with transvaginal color Doppler ultrasound(TVCDS)in diagnosing interstitial infiltration depth and pelvic lymph node metastasis of cervical cancer.Methods:A total of 86 patients with cervical cancer who admitted to Dalian The Fourth People's Hospital between January 2021 and April 2024 were selected as the study subjects,and all of patients received MRI and TVDCS examinations,and the result of pathological examination was used as"gold standard".The diagnostic value of MRI and TVCDS examinations for interstitial infiltration depth and pelvic lymph node metastasis were analyzed respectively.Results:Single MRI,TVCDS,and the combination of them have a certain consistency with postoperatively pathological result in diagnosing the depth of interstitial infiltration of cervical cancer(Kappa=0.735,0.712,P<0.05),while the consistency of the combined examination was the highest(Kappa=0.879,P<0.05).The sensitivity,specificity,and area under curve(AUC)of receiver operating characteristic(ROC)curve of the combined diagnosis of MRI and TVCDS in diagnosing the depth of interstitial infiltration of cervical cancer were respectively 87.46%,90.65%and 0.847(95%CI:0.683-0.957),which were higher respectively than the diagnostic value of each single diagnosis.Single MRI,TVCDS,and the combination of them have a certain consistency with postoperatively pathological result in diagnosing the pelvic lymph node metastasis of cervical cancer,while the highest consistency was observed in the combined examination(Kappa=0.823,P<0.05).The sensitivity,specificity and AUC value of the combination of MRI and VCDS were respectively 89.69%,92.25%,and 0.891(95%CI:0.714-0.968)in diagnosing pelvic lymph node metastasis of cervical cancer,which were higher respectively than the diagnostic value of each single diagnosis.Conclusion:MRI combined with TVCDS is helpful to diagnose the interstitial infiltration depth and pelvic lymph node metastasis of cervical cancer,which can provide important reference for formulating treatment plan of cervical cancer.
