Researchers in this session will describe how torsional wave elastography could be useful in diagnosing skin pathologies.
In his presentation, Guillermo Rus, PhD, from the University of Granada will talk about how this ultrasonic method can noninvasively screen for and extract skin mechanical properties, using biomarkers.
There is a lack of data on the elastic and viscous properties of the skin when pathological conditions such as skin cancer arise. The researchers noted that the collagen, elastin, and cell structures change due to the presence of these pathologies.
Rus and colleagues hypothesized that elastography could noninvasively predict the histopathology of skin tumors. They wanted to present its concept of using torsional shear waves to assess surface and subsurface stiffness by using mechanical biomarkers.
In an initial analysis, the researchers obtained data from 18 patients and used torsional shear waves ranging from 0.4-1 kHz frequencies. They also used elasticity, viscosity, anisotropy, and healthy skin tissue as biomarkers. A larger sample size will be presented at RSNA due to this research being an ongoing study.
βSome results are closely clustered together due to the proximity of the stiffness ratio, but all the results were correlated well with histopathology results,β they wrote.
