Using high-resolution ultrasound imaging to characterize dermal striae in human skin.

Background And Objective: The improvement in the appearance of the skin with dermal striae (DS) is currently eval-uated by invasive methods, such as biopsy. This study evaluates whether high-resolution ultrasound (HRUS) could be used to identify skin lesions in vivo caused by DS, using 2D images and measuring the thickness of the dermal layer.

Methods: High-resolution ultrasound at frequencies of 20 and 30 MHz was used in this study in ten volunteers with DS.
