Three-dimensional ultrasound and three-dimensional power Doppler in the assessment of ovarian tumors.
OBJECTIVE
To determine preoperative method that predicts nature of ovarian tumors.


METHODS
Fifty patients with complex pelvic masses assessed preoperatively with two-dimensional ultrasound (2DUS), two-dimensional power Doppler (2DPD), three-dimensional ultrasound (3DUS), three-dimensional power Doppler (3DPD), color Doppler.


RESULTS
All patients underwent exploration, 19 (38%) had benign tumors, 31 (62%) had ovarian cancer. 2DUS identified 29 cases suspicious for malignancy giving sensitivity, specificity, PPV and accuracy of 80%, 78%, 86%, and 80%. 2DUS with 2DPD identified 28 suspicious cases giving sensitivity, specificity, PPV and accuracy of 80%, 84%, 89%, and 82%. 3DUS identified 31 suspicious cases including 28 cancers giving sensitivity, specificity, PPV and accuracy of 90%, 84%, 90%, and 88%. 3DUS with 3DPD, identified 34 suspicious cases including all 31 cancers giving sensitivity, specificity, PPV and accuracy of 100%, 84%, 91%, and 94%. Color Doppler RI of 0.48 identified 28 cases of 31 cancers giving sensitivity of 90%.


CONCLUSIONS
Evaluation by 3DUS with 3DPD improves diagnostic accuracy of ovarian tumors.
