超声造影在妇科盆腔肿块良恶性鉴别诊断中的应用

Application of Contrast-Enhanced Ultrasound in Differential Diagnosis between Benign and Malignant of Adnexal Masses

目的评价超声造影在妇科盆腔肿块良恶性鉴别诊断中的应用价值。方法分析2008年8月-2009年12月肿瘤妇科收治的43例盆腔肿块患者53个肿块的超声造影检查资料,探讨盆腔良恶性肿块的超声造影表现及超声造影在鉴别诊断中的价值。结果 43例患者53个肿块均经手术病理证实。良恶性肿块的超声造影形态学表现不同。26个良性肿块,大多表现为无增强或自周边向内部逐渐增强,血流规则;27个恶性肿块,多数表现为周边与内部几乎同步充盈,血管粗大扭曲。超声造影检出恶性肿瘤的敏感性为92.3%,特异性96.2%,准确性94.3%,阳性预测值96.2%,阴性预测值92.3%。结论超声造影提供了丰富的肿块血流灌注方面的信息,对于盆腔肿块具有较高的良恶性鉴别诊断价值。

Objective To evaluate the efficacy of contrast-enhanced ultrasound in differentiating malignant from benign adnexal masses. Methods Contrast-enhanced ultrasound examination were performed in 43 patients with 53 adnexal masses. The deference of characteristic between benign and malignant was compared. Results All of 53 masses were confirmed by pathology. Most of 26 benign masses took on the enhancement from periphery into centre and showed regular vessels. Most of 27 malignant masses, rapidly took on the enhancement, came in the centre almost with periphery simultaneous, and showed bulky, tortuous vessels. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value of the discrimination of malignant from benign adnexal masses by contrast-enhanced ultrasound were 92.3% ,96.2% ,94.3% ,96.2% and 92.3% , respectively. Conclusion Contrast-enhanced ultrasound provides informative tumor vaseularity, and can precisely discriminate malignant from benign adnexal masses.
