OBJECTIVE: To evaluate the reproducibility and accuracy of color Doppler flow location in indeterminate masses after a gray-scale sonography in the diagnosis of ovarian malignancy. METHODS: Digitally stored color Doppler sonographic images from a random sample of 130 women with an indeterminate adnexal mass submitted to surgery were evaluated by six different examiners with different degrees of experience. A mass was graded malignant if flow was shown within the excrescences or solid areas. Intraobserver agreement and interobserver agreement according to the level of experience were assessed by calculating the kappa index. RESULTS: Intraobserver agreement was good for all examiners with different degrees of experience (kappa 0.72-0.89). Interobserver agreement was good to moderate for all operators (kappa 0.48-0.71) irrespective of degree of experience. The accuracy was comparable among different operators. CONCLUSIONS: Our results indicate that color Doppler imaging for detection of adnexal malignancy seems to be a reproducible method even in moderately experienced examiners.
