Measurement of Shear Wave Speed and Normalized Elastic Modulus of Human Skin with and without Dermal Striae Using Shear Wave Elastography.

Supersonic shear imaging is a non-invasive technique used for detecting physiologic and pathologic changes in biological tissues. In this study, supersonic shear imaging was used to measure and compare shear wave speed (c) and normalized elastic modulus (E) values of skin with and skin without dermal striae (DS) in vivo. The values were measured at angles of 0°, 45°, 90° and 315° to the skin tension lines.

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.
