Objective To evaluate the clinic value of the high frequency probe and color Doppler flow imaging in the diagnosis of soft tissue masses.Methods One hundred and fifty-four patient with soft tissue masses were analyzed by high-frequency probe and color Doppler flow imaging. All of them were proved by operation, biopsy and pathology. Results Among them, 134 cases were benign lesions and the rest of 20 cases belonged to malignant, The shapes of the benign lesions usually were oval and the boundaries were dearly defined in many lesions. However, the malignant lesions generally were circular and their boundaries were hardly defined. The blood flows usually were less and the peak flow velocities were lower in benign lesions than that in malignant. Conclusion High frequency probe and color Doppler flow imaging are helpful in determining the soft tissue masses location, border, cystic or solid and differentiating from benign and malignant lesions.%目的 探讨高频彩超诊断软组织肿块的临床价值.方法 对154例软组织肿块应用高频探头实施二维灰阶及彩色多普勒超声检查分析,全部病例均经手术或活检后病理证实.结果 良性肿瘤及瘤样病变123例,恶性病变20例.通过灰阶超声比较,良性肿块多为卵圆形,周界清晰,而恶性肿瘤多呈圆形,周界不清.彩超方面,良性肿快较恶性肿瘤血流欠丰富,峰值流速较低.结论 高频彩超能对软组织肿块作出准确定位诊断,判断病变范围及物理性质定性诊断,并有助于鉴别肿瘤的良恶性.
