超声造影在卵巢良恶性肿块鉴别诊断中的应用

目的探讨超声造影在卵巢良、恶性肿块鉴别诊断中的价值。方法采用对比脉冲序列技术(CPS)对55例患者行经阴道二维超声及超声造影检查,观察卵巢病灶或肿块的增强方式与灌注参数的差异;依据患者手术病理诊断结果分为良性组及恶性组,对55例卵巢囊性、囊实性、实性或囊壁乳头病变的二维超声及超声造影图像进行分析比较。结果术前经阴道二维超声诊断卵巢良性肿瘤与病理诊断符合23例(23/28),误诊5例;超声造影诊断卵巢良性肿瘤与病理诊断符合26例(26/28),误诊2例。良性组(28例)造影参数开始增强时间平均为(18.2±4.8)s,达峰时间为(30.5±8.3)s,峰值强度为(11.3±5.0)dB。术前经阴道二维超声诊断卵巢恶性肿瘤与病理诊断符合22例(22/27),误诊4例,漏诊1例;超声造影诊断卵巢恶性肿瘤与病理诊断符合25例(25/27),误诊2例。恶性组27例中24例超声造影开始增强时间为(13.4±4.5)s、达峰时间为(21.5±6.9)s,峰值强度(20.0±5.9)dB,与良性肿块3项造影参数比较差异有统计学意义(P0.05)。结论卵巢良恶性肿块在灌注方式及造影参数上均存在一定的差异,囊性、囊实性、实性及囊壁乳头性病变经阴道二维超声难以鉴别良恶性时,超声造影能反映病变组织微血管的灌注情况,有助于检出早期卵巢癌,并可对常规超声诊断有困难的小型卵巢肿瘤进行鉴别诊断。

The application of contrast enhanced transvaginal ultrasound in the differentiation of benign and malignant ovarian leision

Objective To investigate the value of contrast enhanced transvaginal ultrasound in the differential diagnosis of benign and malignant ovarian lesion. Methods Fifty-five patients with ovarian masse detected by transvaginal ultrasound were enrolled in this study. Each patient received contrast enhanced transvaginalultrasound examination,and the enhancement patterns were analyzed. The patients were classified into two groups according to the pathological findings. The enhancement patterns were compared between...
