Abstract

The aim of the present study was to test the hypothesis that ultrasonic propagation properties in skin and wound tissue would correlate with material properties such as collagen content, water content, and tensile strength of those tissues. Both ultrasonic speed and ultrasonic attenuation coefficient were directly correlated with tissue collagen content, [r = 0.80 and r = 0.56, respectively (p < 0.001)]. In addition, ultrasonic speed and attenuation coefficient were inversely correlated with tissue water content, [r =-0.57 and r = -0.73, respectively (p < 0.001)]. Tensile strength also correlated very significantly with ultrasonic speed (r = 0.90, p < 0.001), and significantly with attenuation coefficient (r = 0.58, p < 0.001). The results demonstrate the feasibility of using ultrasound for noninvasively determining the material properties of biologic tissues including healing cutaneous wounds.
