APPlication Value Of Multimodal Ultrasound For Staging Assessment Of Early Cervical Cancer

Objective Study the evaluation of early cervical cancer lesions and comPare the diagnostic value of multimodal ultrasound and dynamic enhanced magnetic resonance imaging(DCE-MRI)in the evaluation of early cervical cancer staging,to exPlore the aPPlication ProsPect of multimodal ultrasound in PreoPerative staging of cervical cancer.Methods Collect 45 Patients with early cervical cancer from March 2019 to February 2,2023,with Pathological results as the gold standard,according to the standard,Using the 2018 International Union of Obstetrics and Gynecology(FIGO)staging criteria,including IA 2,IB1,IB2,IB3,ⅡA 1,ⅡA 2,together with multimodal ultrasound and dynamic enhanced magnetic resonance imaging(DCE-MRI),to analyze the differences between multimodal ultrasound and dynamic enhanced magnetic resonance imaging and comPare the diagnostic value of multimodal ultrasound and dynamic enhanced MR imaging in early cervical cancer staging.Results 1 The results of dynamic enhanced magnetic resonance imaging were the same as the Pathological results in 41 cases,and the diagnostic accuracy was 91.1%.The KaPPa value of the consistency test was 0.847(P<0.05),which showed good agreement with the Pathological results.2 The results of multimodal ultrasound were the same as the Pathological results in 40 cases,the diagnostic accuracy was 88.8%,and the KaPPa value of consistency test was 0.816 and(P<0.05),which showed good consistency with the Pathological results.3 The diagnostic accuracy of stage IB multimodal ultrasound diagnosis and Pathological diagnosis was 93.9%,and the KaPPa value of the consistency test was 0.895(P<0.05),which showed good consistency with the Pathological results.4.The comparison of IB dynamic magnetic resonance imaging and pathological diagnosis,the diagnosis accuracy was 90.9%,and the KaPPa value of consistency test was 0.840(P<0.05),which showed good consistency with the pathological results.5.The KaPPa value of the consistency test between multimodal ultrasound and dynamic enhanced magnetic resonance imaging was 0.836(P<0.05),and the agreement between the two methods was good.There was no significant difference in the staging accuracy of multimodal ultrasound and dynamic enhanced magnetic resonance imaging for early cervical cancer(P=0.885>0.05).6.Multimodal ultrasound examination has excellent agreement with dynamic MRI in assessing the depth of tumor invasion(r=0.980).Conclusion 1.Multimodal ultrasound examination and dynamic enhanced magnetic resonance imaging have excellent consistency between staging diagnosis and Pathological results of early cervical cancer.2.The accuracy and consistency of multimodal ultrasound examination for staging stage IB cervical cancer is higher than that of dynamic enhanced magnetic resonance imaging.3.Multimodal ultrasound examination has similar PreoPerative staging and dynamic enhanced magnetic resonance imaging results for cervical cancer,which can Provide an imPortant basis for clinical staging and the selection of aPProPriate treatment oPtions.4.Multimodal ultrasound can accurately measure the maximum diameter of cervical cancer tumors,providing a reliable basis for clinical staging.
