Clinically oriented three-step strategy for assessment of adnexal pathology.
To determine the diagnostic performance of ultrasound-based simple rules, risk of malignancy index (RMI), two logistic regression models (LR1 and LR2) and real-time subjective assessment by experienced ultrasound examiners following the exclusion of masses likely to be judged as easy and 'instant' to diagnose by an ultrasound examiner, and to develop a new strategy for the assessment of adnexal pathology based on this. ⋯ A diagnostic strategy using simple descriptors and ultrasound rules when applied to the variables contained in the IOTA database obtains results that are at least as good as those obtained by subjective assessment of a mass by an expert.

Three-dimensional power Doppler ultrasound for the study of cervical cancer and precancerous lesions.
To evaluate the blood flow characteristics of the cervix in normal women and in women with cervical precancerous lesions or cervical cancer. ⋯ 3D-PDU assessment of the cervix reveals significant differences in all indices studied between women with cervical precancerous lesions or cancer and healthy women. In women with cervical cancer, an advanced stage is associated with higher VI, but 3D-PDU indices are not related to other pathological characteristics.
