摘　　要：目的探讨成人正常皮肤声像图及皮肤(表皮和真皮)厚度差异性。方法应用14 MHz高频探头对60名正常成人不同部位皮肤声像图观察,并测量皮肤(表皮+真皮层)的厚度。结果14 MHz高频超声可显示皮肤各层结构。皮肤表皮表现为平滑线状强回声,真皮为低回声带,不同部位皮肤真皮与皮下组织分界清晰或不清晰。表皮和真皮层彩色多普勒血流显像超声未检出血流信号。选择17点部位皮肤观察,其中男女组间12点相同部位皮肤厚度差异具有显著统计学意义。人体不同部位皮肤厚度也存在显著性差异。结论应用高频超声测量皮肤厚度是可行的方法。Objective To evaluate normal skin sonogram and skin thickness at different sites in adult. Methods Skin sonogram was observed and epidermis plus dermis thickness was measured at 17 sites of body in 60 adult healthy volunteers using a 14 MHz ultrasound probe. Results The 14 MHz high-frequency ultrasound showed the structure of skin clearly. The epidermis echo was observed as a strong line smoothly and dermis as a hypoechoic zone. Dermis and subcutaneous tissue boundary were clear or not, depending on different sites. No any blood flow signal in epidermis and dermis was obtained with color Doppler flow imaging sonography. In 17 skin sites, significant difference was found between male and females at 12 sites. Conclusion High-frequency ultrasound is a feasible method for measurement of skin thickness.
