To evaluate the capability of color Doppler ultrasonography to differentiate between benign and malignant soft-tissue tumors.
We reviewed the ultrasonographic (US) and color Doppler (CD) findings in 46 consecutive patients with a palpable periskeletal mass. The presence of 3 or more vascular hila and of tortuous and irregular internal vessels within the lesions was considered an indication of malignancy. The CD diagnosis was compared with that obtained at US alone.
The sensitivity and specificity of CD were respectively 85% and 92%; these values were higher than those obtained at US alone, respectively 75% and 50%. Arteriovenous malformations presented as lesions with large internal vessels that had low vascular impedance and were easily diagnosed. The wave form patterns within solid tumors were not specific.
At present, US is commonly employed to confirm the presence of a suspected soft-tissue mass, to locate it accurately, and to indicate its nature. CD finding enhance the role of the US technique in such lesions. The combined use of US and CD can allow the differentiation of benign from malignant lesions, and thus provide a better basis for treatment.
评估彩色多普勒超声鉴别良恶性软组织肿瘤的能力。
我们回顾了46例可触及骨骼周围肿块患者的超声（US）和彩色多普勒（CD）检查结果。病灶内存在3个或更多血管蒂以及迂曲不规则的内部血管被视为恶性的指征。将彩色多普勒诊断结果与单纯超声检查结果进行比较。
彩色多普勒的敏感性和特异性分别为85%和92%；这些值高于单纯超声检查的结果，单纯超声检查的敏感性和特异性分别为75%和50%。动静脉畸形表现为内部血管粗大、血管阻抗低的病灶，易于诊断。实体瘤内的波形模式不具有特异性。
目前，超声通常用于确认可疑软组织肿块的存在、准确定位并判断其性质。彩色多普勒检查结果增强了超声技术在此类病灶中的作用。超声和彩色多普勒联合使用能够区分良性和恶性病灶，从而为治疗提供更好的依据。
