摘要
目的探讨卵巢良恶性肿瘤的超声造影增强表现。方法超声造影采用编码相位反转技术,对30例常规超声检查发现附件区囊实混合性肿物或实性肿物的患者进行超声造影检查,分析其造影增强特征。结果卵巢良恶性肿瘤超声造影增强表现不同,卵巢良性肿瘤显示瘤体均匀性增强,多数从周边向内部灌注,可见血管形态规则;而恶性肿瘤显示瘤体不均匀性增强,多数以血管为中心向瘤体内部灌注,可见粗大、扭曲、走向不规则的供养血管呈蟹足样或树枝状穿入瘤内。结论卵巢良恶性肿瘤的超声造影增强表现不同,有助于卵巢肿瘤良恶性鉴别及早期卵巢癌的发现。
Objective To discuss the enhanced appearance of contrast - enhanced ultrasound on ovarian benign tumors and malignant tumors. Methods 30 women with suspected complex adnexal masses agreed to undergo contrast - enhanced ultrasound （CEUS） examination by use of the Cede PI mode. The enhancement appearance of CEUS was observed on tumors. Results The enhanced appearance of contrast - enhanced ultrasound on malignant tumors and benign tumors is different. The benign ovarian tumors take on the enhancement of contrast agent regularly from periphery into centre and show normal vessel calibers, while malignant tumors take on the enhancement irregularly on vascular as centre and show heterogeneous features including bulky, tortuous, irregular calibe.r vascular pattern which look like crab feet or branches. Conclusions The enhanced appearance of contrast - enhanced ultrasound on malignant tumors and benign tumors is different, which is helpful in differentiating ovarian malignant tumors from benign tumors and finding ovarian cancer in earlier period.
