Abstract：Objective:To investigate the diagnostic value of combined transvaginal three-dimensional ultrasound(3D-TVS)and shear wave elastography(SWE)in distinguishing benign from malignant ovarian tumors.Method:A total of 80 patients with ovarian tumors diagnosed by surgical pathology at Dongguan Ren Kang Hospital between January 2024 and January 2025 were selected.Based on pathological findings,they were divided into a benign group(n=40)and a malignant group(n=40).Using the Philips EPIQ 7C ultrasound system for 3D transvaginal ultrasound(TVS)and shear wave elastography(SWE)examinations,the tumor's morphological characteristics(cystic-solid ratio,intraluminal papillary structures,blood flow grading)and elasticity parameters(Emean,Emax,Emin)were assessed.The diagnostic efficacy of single versus combined methods was compared.Result:The area under curve of the combined model was significantly higher than that of either 3D-TVS or SWE alone.The malignant group exhibited higher Emean,cystic-solid ratio,and proportion of grade 2-3 flow compared to the benign group.The combined model demonstrated the highest sensitivity and specificity,with statistically significant differences(P<0.05).Conclusion:The combination of 3D-TVS and SWE significantly improves the accuracy of distinguishing benign from malignant ovarian tumors,with its multimodal parameter integration strategy providing a reliable basis for noninvasive clinical diagnosis.
