Abstract:
Objective To compare the value of ultrasound International Ovarian of Tumor Analysis (IOTA) simple rules and gynecologic imaging reporting and data system (GI-RADS) ultrasonographie stratification in the diagnosis of adnexal masses.Methods A total of 463 patients with adnexal masses were classified according to IOTA simple rules by senior doctor.The benign and malignant masses were enrolled in the study.Then the masses were judged according to GI-RADS classification and IOTA simple rules by senior and junior doctors.And junior doctorn in diagnosis of adnexal masses with IOTA was group A1,senior doctor in diagnosis of adnexal masses with IOTA was group B1,junior doctor in diagnosis of adnexal masses with GI-RADS was A2,senior doctor in diagnosis of adnexal masses with GI-RADS was B2.The efficacy of the two methods were compared.Results Among the 463 cases,there were 411 cases (411/463,88.77％) of benign mass and malignant mass by IOTA and 52 cases (52/463,11.23 ％) of uncertain mass.The specificity,positive predictive value,diagnostic accuracy had statistical differences between groups A2 and B2,A1 and A2 (all P＜0.05),and sensitivity and negative predictive value had no statistical differences (all P＞0.05).Diagnostic efficacy index had no statistial signifi cance between group A1 and B1,B1 and B2 (all P＞0.05).Conclusion The diagnostic efficacy of IOTA simple rules and GI-RADS is high and similar in diagnosis of benign and malignant adnexal masse.IOTA simple rules do not depend on experience,but they are not suitable for the diagnosis of all adnexal masses.
