Cross-Sectional Nakagami Images in Passive Stretches Reveal Damage of Injured Muscles

Figure 2

Ultrasonography was obtained by high frequency ultrasound (HFU) from longitudinal and cross sections of normal and injured muscles at the original length (a). The ultrasound images were presented as echogenicity (upper row) and Nakagami (lower row) images to indicate the tissue property. In longitudinal sections, both echogenicity and Nakagami were significantly decreased in the injured muscles (b). The injured muscle also showed decreased echogenicity and Nakagami parameters when acquiring the ultrasonic images in cross section (c). : significant difference () from the normal muscle, bar = 1 mm.
