彩色多普勒能量图 (ＣｏｌｏｒＤｏｐｐｌｅｒＥｎｅｒｇｙ ,ＣＤＥ)因其能量信号的显示较少受角度影响 ,显示血管的连续性好 ,并能显示低流量、低流速的血流 ,常用于末稍低流速血流信号的显示[1 ,2 ] 。本组为 1998年 2月— 1999年 7月我院首程放疗的鼻咽癌伴颈淋巴结转移患者
Color DopplerEnergy (CDE) is less affected by angle because of its energy signal display. It shows good continuity of blood vessels and can show low-flow, low-flow blood flow. It is commonly used in low-flow-rate blood flow Signal display [1, 2]. This group is February 1998 - July 1999 first hospital radiotherapy of nasopharyngeal carcinoma with cervical lymph node metastasis
