A prospective comparative study between 3D ultrasonography and traditional 2D ultrasonographic assessment of ovarian tumours

Objective: to evaluate the value of 3D ultrasonographic examination of adnexal masses compared to 2-dimensional ultrasound. Design: prospective clinical study Setting: Kasr El-Aini hospital, CairoUniversity Materials and methods: One hundred women with postmenopausal bleeding were subjected to two dimensional ultrasound and 22 women with ovarian masses were further examined by 3-D ultrasonographic evaluation. Then the findings were compared to histopathological examination of tissue specimens. Data obtained were then analyzed Results: malignant lesions were found in 7 cases; benign lesions in 13 cases and non-neoplastic lesions in 2 cases (PID and endometrioma). Out of the seven malignant cases; five were cystadenocarcinoma. At cut-off points of 9 and 7 for 2D and 3D respectively achieved 85% sensitivity and 80% specificity Conclusion: 3D ultrasonography has the potential to be a supplement to 2D ultrasonography and might be useful in identifying malignant ovarian tumors. Large scale studies are needed to confirm our finding
