Multicenter Study Observational StudyIntra- and interobserver agreement with regard to describing adnexal masses using International Ovarian Tumor Analysis terminology: reproducibility study involving seven observers.
To estimate intraobserver repeatability and interobserver agreement in assessing the presence of papillary projections in adnexal masses and in classifying adnexal masses using the International Ovarian Tumor Analysis terminology for ultrasound examiners with different levels of experience. We also aimed to identify ultrasound findings that cause confusion and might be interpreted differently by different observers, and to determine if repeatability and agreement change after consensus has been reached on how to interpret 'problematic' ultrasound images. ⋯ Despite uncertainty about how to define solid components, interobserver agreement was good for tumor type. The interobserver agreement for papillary projection was moderate but very variable between observer pairs. The term 'papillary projection' might need a more precise definition. The consensus meeting did not change inter- or intraobserver agreement.
