分析10例肾癌(9例直径>6cm)的彩色多普勒超声的基本特征,血流类型以彩球型为主,散点型次之;肿瘤内出现动脉+静脉两种血流信号;较大肿瘤以动脉高速者居多;肿瘤血管流速大于同侧肾动脉流速.
The basic features of color Doppler ultrasound in 10 cases of renal cell carcinoma (9 cases> 6 cm in diameter) were analyzed. The main types of blood flow were color ball type and scattered type followed by arterial + venous blood flow signals. Larger tumors are mostly arterial high-speed; tumor blood flow velocity is greater than ipsilateral renal artery flow velocity.
