Official Title: Regional Study Into the Performance and Cost-effectiveness of Simple Ultrasound-based Rules Compared to the Currently Used Risk of Malignancy Index in the Diagnosis of Ovarian Cancer
Brief Summary: This study is performed to compare the diagnostic performance and cost-effectiveness of different diagnostic methods for differentiating benign from malignant adnexal (ovary or Fallopian tube) masses: the Risk of Malignancy Index (RMI) will be compared with a two-step triage test called "simple ultrasound-based rules" supplemented -if necessary- with either subjective assessment by an expert sonographer or Diffusion Weighted - Magnetic Resonance Imaging (DW-MRI). The investigators will test the hypothesis that this two-step triage test will have better diagnostic accuracy than the RMI and therefore will improve the management of women with adnexal masses.
