About this trial
Multicenter prospective cohort study in which patients ≥18 years with an ovarian tumor for which an ultrasound has been performed in accordance with IOTA criteria and the IOTA ADNEX model has been applied are included. Ultrasound data from these patients will be prospectively recorded in a database to determine the diagnostic accuracy of the IOTA ADNEX model in Dutch gynaecological practice.

Treatments tested in this trial
Observational study. Prospective registration of ultrasound data in patients with ovarian tumors for which an ultrasound in according with the IOTA definitions is performed.
