超声造影在卵巢肿瘤及卵巢蒂扭转诊断中的应用

The clinical value of contrast-enhanced ultrasound in diagnosis of ovarian and ovarian tumors torsion

目的探讨超声造影诊断卵巢肿瘤及卵巢蒂扭转的声像学特征及临床应用价值。方法采用对比剂Sonovue及低机械指数成像技术对32例怀疑卵巢肿瘤及卵巢蒂扭转的患者进行超声造影检查,分析其造影特点并与手术病理结果对照。结果 32例患者术后3例卵巢复活成功,其中常规彩色多普勒超声检查2例肿块周边及内部探及少量血流信号,超声造影检查5例病灶内见对比剂充填,表现为增强早期呈不均匀低增强,增强水平低于子宫肌层,增强晚期呈明显低增强。彩色多普勒超声与超声造影两种检查对诊断卵巢肿瘤蒂扭转之间具有一定程度的一致性(κ=0.529,P=0.248)。结论卵巢肿瘤及卵巢蒂扭转超声造影增强模式具有特征性,可显示内部组织缺血坏死的改变,较彩色多普勒对内部有无血供更敏感,为诊断提供更准确的信息,增加诊断信心。

Objective To observe the appearance and characteristics of ovarian and ovarian tumors torsion on contrast-enhanced ultrasound（CEUS） and to analyze its diagnostic value. Methods ovarian and ovarian tumors torsion proven pathologically in 30 cases were studied and analyzed with real-time harmonic ultrasonographic imaging under a low mechanical index. Results 32 cases of patients with postoperative 3 cases of ovarian resurrection success, including conventional color doppler ultrasound 2 cases of peripheral and internal agent and a small amount of blood flow signals, contrast-enhanced ultrasound examination in 5 cases lesions in contrast filling, enhancement level lower and that of myometrium and strengthen the terminal was significantly enhanced. The two methods showed a certain degree concordance （κ=0.529, P=0.248）. Conclusions The CEUS allows a more complete display of the vascular patterns in ovarian and ovarian tumors torsion. Contrast-enhanced ultrasonography with color doppler more sensitive to mass inside presence of blood supply, to provide more accurate information for diagnosis, to increase diagnostic confidence.
