Diagnostic value of transvaginal three-dimensional ultrasound combined with color Doppler ultrasound for early cesarean scar pregnancy

Additionally, the sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve (AUC) in the Combination group were higher than those in the Control group. Transvaginal 3D-US combined with color Doppler US can improve the sensitivity, specificity, and accuracy of diagnosis of early CSP, and has important reference value for clinical condition evaluation and treatment options.
