目的:检测大肠癌患者的肝脏血流灌注指数(DPI),探索大肠癌肝转移患者DPI变化的规律。
Objective: To investigate the variation of doppler Perfusion Index (DPI) in patients with liver metastases of colorectal carcinoma by color doppler sonography.
目的:应用多普勒超声测定多普勒血流灌注指数(DPI)、阻力比(RR)等血流参数,用以评价其对肝癌术后复发患者的诊断价值。
Purpose:To assess the value of the DPI and RR measured with Doppler Ultrasound (DUS) in diagnosing recurrent primary hepatocellular carcinoma after partial hepatectomy.
