Comparison of Two-Dimensional IOTA Simple Rules and Three-Dimensional Ultrasonography in Preoperative Assessment of Adnexal Masses

Abstract

Objective Accurate preoperative characterization of adnexal masses is essential for optimal patient management. Two-dimensional ultrasonography (USG) based “International Ovarian Tumuor Analysis Simple Rules (IOTA-SR)” are used primarily in clinical practice. Three-dimensional (3D) USG is an emerging modality. The authors conducted this study to compare the performance of 3D USG with IOTA-SR for preoperative differentiation of benign and malignant adnexal masses.
