彩色多普勒能量图及其三维彩色能量成像在肾脏肿瘤诊断中的应用

目的 :探讨彩色多普勒能量图及其三维彩色能量成像在肾脏肿瘤中的应用。方法 :用彩色多普勒能量图观察肾脏肿瘤 2 8例 ,之后对其中 2 1例肾癌进行三维彩色能量成像观察。结果 :彩色多普勒能量图显示 86 %肾癌内部血流丰富 ,其中 级血流占 6 2 % ,而肾良性肿瘤血流分级为 0～ 级。 86 %肾癌三维彩色能量成像显示出“珊瑚状”立体构架图 ,可获得较为直观、完整的立体血管网图像。结论 :彩色多普勒能量图及其三维彩色能量成像较直观、完整地显示肾脏肿瘤血流状态 ,灵敏度高、连续性好 ,为肾脏肿瘤的良、恶性判断上提供更多的信息量

The Role of Color Doppler Energy and Three-dimensional Color Power Angiography in the Diagnosis of Renal Neoplasm

Objective:To evaluate the clinical value of color Doppler energy (CDE) and three dimensional color power angiography (3D CPA) in the diagnosis of renal neoplasm.Methods:28 cases with different kinds of renal neoplasm were examined by CDE,and 21cases were also surveyed by 3D CPA.Results:86% of renal neoplasm showed high blood perfusion,62% of them were high grade perfusion,but all the benign renal tumors were low grade perfusion. 86% 3D CPA of renal neoplasms can display "coral" cube construction. 3D CPA stereoscopically showed the network of cancer blood vessels.Conclusions:CDE and 3D CPA can audio visually display renal neoplasm blood vessles because of its fair sensitivity,and it may nicely distinguish the malignant renal neoplasm from benign tumor.
