Peripheral nervous system
The imaging of the peripheral nervous system includes the representation of the nerve plexus in the neck (plexus cervicobrachialis) and in the lumbar spine (lumbosacral plexus), and the more peripheral nerves located in the arm and leg. Plexus lesions usually develop as a result of inflammation, tumours or injuries (e.g. motorcycle accident).
Lesions of the major nerves in the arm can be detected using MR tomography (ulnar nerve, median nerve, axillary nerve, musculocutaneus nerve). The ulnar nerve in the elbow is often affected (sulcus ulnaris syndrome), as well as the median nerve in the hand (carpal tunnel syndrome), and less frequently the ulnar nerve (Loge de Guyon syndrome). More often than not a compression injury of the peroneal nerve is present during peroneal paralysis in the lower leg (e.g. when in a prolonged kneeling position, position during surgery, among other things).
