Real-time visualization of muscle stiffness distribution with ultrasound shear wave imaging during muscle contraction.

abstract：INTRODUCTION:The aim of this study was to evaluate the ultrasound (US) morphological changes of sural nerves (SNs) of uremic patients on hemodialysis. METHODS:Sixty-six SNs in 33 uremic patients were examined by 22-MHZ high-frequency US and routine nerve conduction studies (NCS), and 76 SNs in 38 controls were also ex...
