三维能量多普勒直方图鉴别诊断卵巢肿物良恶性的价值

目的应用三维能量多普勒直方图定量测量卵巢肿物血管参数,并评价其鉴别诊断卵巢肿物良恶性的价值及与临床分期的关系。方法应用三维能量多普勒超声在术前1周内对57例卵巢肿物患者进行检查,测量肿物内实性部分的血管参数,包括血管形成指数(VI)、血流指数(FI)、血管形成-血流指数(VFI)。比较卵巢良性与恶性肿物之间血管参数的差异及其与临床分期的关系。结果 57例患者中共检出卵巢肿物62个(双侧卵巢肿物5例),经病理证实为良性肿物22个(良性组),恶性肿物40个(恶性组,包括交界性肿瘤8个)。恶性组肿瘤VI(6.3±5.9)%、FI(32.0±8.6)和VFI(2.4±2.7)测值均明显高于良性组肿物VI(2.1±3.3)%、FI(21.0±12.5)和VFI(0.7±1.1),差异有统计学意义(P均<0.01)。以VI>2.1%为界值鉴别卵巢肿瘤良恶性的灵敏度和特异度分别为80.0%、73.0%;卵巢癌FIGO分期Ⅰ、Ⅱ期肿瘤与Ⅲ、Ⅳ期肿瘤VI、FI和VFI测值比较差异均无统计学意义。结论三维能量多普勒直方图是术前评估卵巢肿物良恶性的新方法,可为其提供有价值的信息,但不能术前评估卵巢癌分期情况。

The value of differentiating benign and malignant ovarian tumors with three-dimensional power Doppler histogram

Objective To evaluate and compare intratumoral vascularization index (VI), flow index(FI) and vascularization-flow index (VFI) of benign and malignant ovarian tumors with three-dimensional power Doppler histogram. Methods Fifty-seven patients with ovarian tumors were evaluated by three-dimensional power Doppler ultrasound during one week before surgery. The VI, FI and VFI were compared between the malignant tumors of different stages and benign tumors. Results Sixty-two ovarian tumors in Fifty-seven women w...
