Abstract：Objective: To investigate the diagnostic value of contrast-enhanced ultrasound(CEUS) for benign and malignant ovarian tumors． Methods: Fifty ovarian tumors were evaluated with contrast-enhanced ultrasound. Enhancement patterns in benign and malignant ovarian tumors were analysed． Results: The centrifugal enhancement were typically presented in malignant ovarian disease. Sensitivity, specificity, accuracy, PPV, NPV of centrifugal enhancement for the diagnosis of malignant ovarian tumors were 87.50％, 100％, 96.00％, 100％, 94.44％; and the circular enhancement were typically presented in benign ovarian tumors, diagnostic value of circular enhancement for the diagnosis of benign ovarian tumors were 84.62％, 87.50％, 86.00％, 88.00％, 84.00％. The diagnostic accordance rate of benign and malignant ovarian tumors were significant between contrast-enhanced ultrasound and baseline ultrasound(P<0.05）. Conclusion: Centrifugal enhancement and circular enhancement are highly suggestive of malignant ovarian tumors and benign ovarian tumors respectively.
