【摘要】 目的　探讨 2 0MHz高频超声探头对皮肤结节性红斑的诊断价值。方法　应用 2 0MHz高频超声对 2 6例经穿刺活检组织学检查的皮肤结节性红斑患者进行了动态观察。结果　急性型 (早、中、晚期 )和慢性型结节性红斑患者有不同的声像图特征。结论　①高频超声可对结节性红斑病变的程度及分期作出估价 ;②其声像图表现与病理特点相关 ,提示高频超声检查为皮肤病变的诊断提供了一种新的无创性的检查手段。更多还原

【Abstract】 Objective To evaluate the value of high frequency ultrasound for dignosing erythema nodosum(EN).Methods Twenty six cases with EN confirmed by biopsy were studied by high frequency ultrasound imaging.Results Acute type(early,middle,and late stage)had a different sonographic feature when compared to chronic one. Conclusions High frequency ultrasound has an important clinical value for the diagnosis of grade and degree of EN. The featunes of sonographic image in EN are in consistent with the pathological findings, indicating that it is a new convenient and non invasive method for the diagnosis of skin lesions.更多还原
