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.
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.
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.
Our results indicate that color Doppler imaging for detection of adnexal malignancy seems to be a reproducible method even in moderately experienced examiners.
评估灰阶超声检查后彩色多谱勒血流定位对卵巢恶性肿瘤诊断中不确定性质肿块的重复性和准确性。
对随机抽取的 130 例行手术的附件区不明性质肿块的妇女的数字化存储彩色多谱勒超声图像，由六位不同经验程度的检查者进行评估。如果在赘生物或实性区域内显示血流，则将肿块评为恶性。通过计算 Kappa 指数评估不同经验水平的观察者内和观察者间的一致性。
所有不同经验程度的检查者的观察者内一致性均较好（Kappa 值为 0.72-0.89）。所有操作者的观察者间一致性均为较好至中度（Kappa 值为 0.48-0.71），与经验程度无关。不同操作者之间的准确性相当。
我们的结果表明，即使在经验程度中等的检查者中，彩色多谱勒成像检测附件区恶性肿瘤似乎也是一种可重复的方法。
