Improving the performance of IOTA simple rules: sonographic assessment of adnexal masses with resource-effective use of a magnetic resonance scoring (ADNEX MR scoring system).

Although this study leaves no doubt about the superiority of MR score over US-based methods for the discrimination of malignant tumors in women with adnexal masses, restricting the use of MR score only to women with indeterminate masses on US SR is a safe, appropriate way to triage women with adnexal masses.
