Application of Transvaginal Conventional Ultrasound Combined with Three-dimensional Energy Doppler Ultrasound in the Differential Diagnosis and Prognostic Evaluation of Ovarian Tumors
Objective:To investigate the value of transvaginal conventional ultrasound combined with three-dimensional energy Doppler ultrasound(3D-PDUS)in the differential diagnosis and prognostic evaluation of ovarian tumors.Methods:The clinical data of 104 patients with ovarian tumors admitted to the hospital from October 2019 to October 2022 were retrospectively analyzed and divided into malignant group(33 cases)and benign group(71 cases)according to pathological diagnosis.The diagnostic data of transvaginal conventional ultrasound and 3D-PDUS were compared between the two groups of patients,and the value of transvaginal conventional ultrasound combined with 3D-PDUS in the differential diagnosis of ovarian tumors was explored.Results:The percentage of lesions with irregular shape,the percentage of solid/cystic solid internal echogenicity,and the percentage of having ascites in the malignant group were greater than those in the benign group,and the difference was statistically significant(χ2=7.462,12.726,8.255;P＜0.05).The vascular flow index(VFI),flow index(FI),and internal vascular index(VI)of the malignant group were higher than those of the benign group,and the differences were statistically significant(t=7.279,5.018,6.915;P＜0.05).The results of logistic regression analysis showed that transvaginal routine ultrasound signs of lesion shape,internal echoes,ascites,and 3D-PDUS parameters VFI,FI,and VI were associated with the benign and malignant nature of ovarian tumors(OR＞1,P＜0.05).The working curve(ROC)of the subjects showed that the area under the curve(AUC)of the combined diagnostic regression model to identify benign and malignant ovarian tumors was 0.905,which has some diagnostic value.Conclusion:Both routine transvaginal ultrasound signs and 3D-PDUS parameters can be used to identify ovarian tumors,and the combination of the two has high application value in the differential diagnosis and prognostic evaluation of ovarian tumors.
