1. Lumbosacral plexopathy traditional diagnosis relies on clinical findings; and electrodiagnostic test results. 2. Electrodiagnostic tests provides only a limited evaluation due to deep location of target nerves and the variable innervation of the muscular groups. 3. Current role of MRN in plexopathy relies on the reliable recognition of normal and abnormal patterns based on: nerve root signal intensity, nerve root thickness, root course, perineural soft tissue appearance and dependent muscular groups appearance . 4. Nowadays, information provided by MRN offers a solid morphologic aid in clinical or pre-surgical evaluation and patient management  

1. Technique and Parameter and Post processing overview, 2. Magnetic resonance neurography (MRN) findings in a cohort of healthy volunteers 3. MRN features of (LSP) plexopathy in subjects with abnormal clinical features and EMG positive test. 4. Illustrative clinical examples showing clinical, EMG and MRN discrepancies. 5. Summary of key features for the interpretation of the pathological results of lumbosacral MRN
