Abstract

Ultrasonography is a recognized method of tissue visualization in medicine, which is based on the use of mechanical waves (ultrasound). Its application in dermatology requires the use of higher frequencies, hence the use of high-frequency ultrasonography (HFUS) is recommended. HFUS has gained approval in many areas of dermatology, including imaging of skin appendages [nail unit (NU) and hair follicles]. The analysis of the changing echogenicity of structures under the influence of inflammatory and neoplastic processes is used to assess the extent of the disease, treatment planning as well as in monitoring therapeutic effects. The aim of our work is to present the possibilities of visualizing NUs and scalps with the use of HFUS.
