ISCU is a recently established member organization which aims to promote the use of high frequency and ultra-high frequency ultrasonography (HFUS and UHFUS) in dermatology. The aim of ISCU is to develop a multidisciplinary international network to disseminate the knowledge on the ultrasonographic study of skin and subcutaneous tissue, to better understand the evolution of skin diseases from early to advanced stages, allowing early diagnoses and correct ultrasound-guided treatments. Bridging the gap between diagnosing and treatment to exploit the potential of implementing ultrasound techniques for skin.
