Shear Wave Elastography, a New Tool for Diaphragmatic Qualitative Assessment: A Translational Study

Prolonged mechanical ventilation is often associated with either a decrease (known atrophy) or an increase (supposed injury) in diaphragmatic thickness. Shear wave elastography is a noninvasive technique that measures shear modulus, a surrogate of tissue stiffness and mechanical properties. Here, th...

Description
Summary:Prolonged mechanical ventilation is often associated with either a decrease (known atrophy) or an increase (supposed injury) in diaphragmatic thickness. Shear wave elastography is a noninvasive technique that measures shear modulus, a surrogate of tissue stiffness and mechanical properties. Here, the study by Aarab et al that describes changes in shear modulus (SM) during the ICU stay and the relationship with alterations in muscle thickness is highlighted.
