【摘要】：目的用无创高频超声自动测量中国健康人群各年龄组皮肤厚度、皮肤回声密度及皮肤声像图研究。方法应用22 MHz高频超声分别对830例健康人群前额、面颊、前臂、手背、手掌、腹部、小腿、脚背8个不同解剖部位进行自动测量皮肤厚度、皮肤回声密度及皮肤声像图观察,并详细记录各组数据。结果 22 MHz高频超声可以清晰地显示皮肤各层结构:表皮层为一线状高回声,真皮层为中等回声,真皮下层可见管状低回声的皮下静脉,皮下脂肪层为低回声,浅筋膜为规则纵向走行的线状高回声。部位不同、性别不同均影响皮肤厚度且差异均有统计学意义(P0.05)。除面颊与手掌、前臂与手背、小腿与脚背,其它部位两两之间皮肤回声密度比较差异有统计学意义(P0.05)。除脚背部,其它部位性别不同其皮肤回声密度差异有统计学意义(P0.05)。结论 22 MHz高频超声可以清晰地显示皮肤各层结构及精确地测量皮肤厚度和皮肤回声密度。
[Abstract]:Objective to study the thickness of skin, echo density of skin and sonogram of skin in different age groups of healthy Chinese population by using non-invasive high-frequency ultrasound. Methods the forehead, cheek, forearm, back of hand, palm of 830 healthy people were studied by 22 MHz high-frequency ultrasound. The thickness of skin, echo density and sonogram of skin were measured automatically at 8 different anatomical sites of abdomen, calf and back of foot. Results 22 MHz high frequency ultrasound could clearly show the structure of each layer of skin: the epidermis was a linear hyperechoic cortex, the dermis was a medium echo, the subdermal subdermal vein was tubular hypoechoic, and the hypoechoic subcutaneous vein could be seen in the subdermis. The subcutaneous fat layer is hyperechoic, and the superficial fascia is linear hyperechoic in a regular longitudinal walk. The skin thickness is affected by sex, and the difference is statistically significant (P 0.05) except cheek and palm, forearm and back of hand, leg and foot. There was significant difference in skin echo density between other parts (P 0.05). Except for the back of the foot, there was no significant difference in the skin echo density between the two parts. Conclusion 22 MHz high frequency ultrasound can clearly display the skin structure and accurately measure the skin thickness and echo density.
