Development of methods for predicting muscle strength using thetexture information of Ultrasound echo image

点击翻译按钮获取中文摘要

Muscle strength is determined by muscle quantity and quality. The present study examined whether image textures seen by B-mode ultrasound echo include information of muscle quality in the anterior thigh (rectus femoris and vastus intermedius muscles). Some parameters in the image textures showed a relationship to age and muscle strength of knee extension. These findings suggested that combination of information from the image textures and muscle quality (e.g. muscle thickness) can assess muscle strength and aging.
