彩色多普勒超声对皮肤血管瘤的诊断价值

本文报道应用彩色多普勒超声对２１个皮肤血管瘤的检测结果。小的单纯血管瘤瘤体近圆形、大的海绵状血管瘤多不规则，均无明显包膜回声，内部回声低而不均，８个瘤体侵犯了深部组织。小的瘤体比大的瘤体易于获取血流信号，彩色多普勒能量图（ＣＤＰＩ）敏感性优于彩色多普勒血流显像（ＣＤＦＩ）。在１７个瘤内可记录到的动脉频谱中，其平均最大流速为１１．３ｃｍ／ｓｅｃ（４．１～１５．５ｃｍ／ｓｅｃ），平均阻力指数为０．６５（０．５９～１．０）。

The Value of Color Doppler Ultrasonography in Diagnosis of Dermatohemangioma

Twenty-one dermatohemangiomas were examined by color Doppler ultrasonography.The small simple hemangioma was round,the big canverous hemangioma was irregular.Both present low or inhomogenous echogenicity and devoid of capsule.The deep tissues were invaded in 8 tumors.It is easy to catch the blood flow signals in the small tumors than the big ones.The sensitivity of the color Doppler power imaging is higher than the color Doppler blood flow imaging.The average maximum blood flow velocity is 11 3cm/sec(4 1-15 5cm/sec)and the average resistance index is 0 65(0 59-1 0).
