Subjective assessment of adnexal masses with the use of ultrasonography: an analysis of interobserver variability and experience

Abstract

Experienced ultrasonographers using some clinical information and their subjective assessment of ultrasonographic images can differentiate malignant from benign masses in most cases. The accuracy and the level of interobserver agreement are both correlated with experience. About 10% of masses were extremely difficult to classify (only < 50% of assessors were correct).
