多普勒超声可检测恶性肿瘤的血管特性,已用于乳腺癌的诊断和处理,本文报告用一种新型含微气泡的造影剂(含SHU 508A,微泡直径<10μm),评价其在鉴别良恶性肿瘤中的作用。怀疑乳腺病变的病人34例,经外周血管注射含微气泡的造影剂10ml,注射速度为2ml/s,含SHU300mg/ml。进行彩色多普勒超声检查,研究造影前后彩色多普勒信号(C0)增强程度、微气泡群作用时间(多普勒信号达最大所需时间和增强持续的时间)以及血管特性如血管数目、血管弯曲度和血
Doppler ultrasound can detect the vascular characteristics of malignant tumors, and has been used for the diagnosis and treatment of breast cancer. This paper reports the use of a novel microbubble-containing contrast agent (including SHU 508A, microbubble diameter <10μm) to evaluate its identification. The role of benign and malignant tumors. Thirty-four patients with suspected breast lesions were injected with 10 ml of contrast medium containing microbubbles via the peripheral blood. The injection rate was 2 ml/s and contained 300 mg/ml of SHU. Color Doppler ultrasonography was used to study the enhancement of color Doppler signal (C0) before and after angiography, the duration of micro-bubble groups (maximal time required for Doppler signal and duration of enhancement), and the characteristics of blood vessels such as blood vessels. Blood vessel curvature and blood
