For evaluating abdominal hemodynamic changes and diagnosing mass lesion, recently color Doppler ultrasonography (CDUS) have been applied. However, there are limitations in visualizing Doppler signals in small vessels with low flow velocity. To overcome these shortcomings, several contrast agents that facilitate evaluation of abdominal hemodynamics have been developed. We underwent Contrast enhanced color Doppler ultrasonography (CECD) with a galactose-based contrast agent in three patients with pancreatic tumor. In the patient with tumor forming pancreatitis, only CECD visualized the color signal in and around the tumor. In the patient with duct cell cancer, CDUS and CECD visualized only the color signal of the splenic artery penetrating the tumor, whereas in the patient with islet cell tumor, CECD visualized numerous color signals in the tumor. CECD appears to be useful in diagnosing pancreatic tumor.
为了评估腹部血流动力学变化并诊断肿块病变，近年来彩色多普勒超声检查（CDUS）已被应用。然而，在可视化低流速小血管中的多普勒信号方面存在局限性。为了克服这些缺点，已经开发了几种有助于评估腹部血流动力学的造影剂。我们对三名胰腺肿瘤患者使用基于半乳糖的造影剂进行了超声造影增强彩色多普勒超声检查（CECD）。在肿瘤形成性胰腺炎患者中，只有CECD能显示肿瘤内及周围的彩色信号。在导管细胞癌患者中，CDUS和CECD仅能显示穿透肿瘤的脾动脉的彩色信号，而在胰岛细胞瘤患者中，CECD能显示肿瘤内大量的彩色信号。CECD似乎对胰腺肿瘤的诊断有用。
