title: [Physical principles and general considerations].
abstract: Cutaneous ultrasound is based on the application of the physical properties of ultrasound to the skin and cutaneous adnexae. Knowledge of ultrasound semiology, artifacts and the application of Doppler examination allows deeper study of the biology and diseases of the skin and its adnexae.
