超声造影增强模式对卵巢肿瘤的诊断价值

Diagnostic value of contrast-enhanced ultrasound in ovarian tumors

目的:探讨超声造影对卵巢良恶性肿瘤的诊断价值。方法:对50个卵巢肿瘤进行超声造影检查,分析卵巢良恶性肿瘤的超声造影增强模式。结果:卵巢恶性肿瘤造影增强模式多表现为离心性增强,超声造影离心性增强对卵巢恶性肿瘤诊断的敏感性、特异性、准确性﹑阳性预测值及阴性预测值分别为87.50%、100%、96.00%、100%及94.44%;卵巢良性肿瘤造影增强模式多表现为环状增强,环状增强对卵巢良性肿瘤诊断的敏感性、特异性、准确性、阳性预测值及阴性预测值分别为84.62%、87.50%、86.00%、88.00%及84.00%。超声造影对卵巢良恶性肿瘤的检出率与常规超声比较差异均有统计学意义(P<0.05)。结论:超声造影离心性增强及环状增强分别对卵巢恶性肿瘤和良性肿瘤有较高的诊断价值。

Objective： To investigate the diagnostic value of contrast-enhanced uhrasound（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%, 86.00v/c, 88.00%, 84.00%. Tile 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 cireular enhancement are highly suggestive of malignant ovarian tumors and benign ovarian tumors respectively.
