Objective assessment of leg edema using ultrasonography with a gel pad
Fig 3
Edema can be identified in subcutaneous tissues due to non-homogeneous echogenicity in comparison with homogeneous echogenicity of the gel pad before the intervention (A). Subcutaneous tissues become homogeneous after the intervention (B). In a younger adult, normalized subcutaneous echogenicity after the intervention (1.15 ± 0.02) was lower than that (1.21 ± 0.07) before the intervention. Mean normalized subcutaneous echogenicity (1.31 ± 0.18) in A was lower than that (1.38 ± 0.16) in B. A. Before the intervention. B. After the intervention. C. Gel pad. D. Subcutaneous tissue.
