 The use of nerve ultrasound for the diagnosis and monitoring of neuromuscular diseases is a promising growing field 1. Non-invasive and painless, ultrasound provides additional data electroneuromyography EMG, with a spatial resolution at least as good as MRI, while being easily accessible and inexpensive.The polyradiculoneuritis Inflammatory Demyelinating Chronicles IPDC, Neuropathies Motrices in Multifocal Conduction Blocks NMMBC and neuropathy associated with anti-MAG antibodies are among the major chronic inflammatory neuropathies with an autoimmune etiology. The diagnosis of these pathologies is based on the clinic, diagnostic tests and EMG. The interest not only in the diagnosis, but also for monitoring these pathologies using ultrasound analysis nerves has been demonstrated recently in several studies. However the limited resolution of current ultrasound images do not allow detailed study of the internal structure of the nerves which could later help deepen knowledge in this innovative field and can better understand the pathophysiological mechanism of the evolution of these pathologies .
