Demystifying MR Neurography of the Lumbosacral Plexus: From Protocols to Pathologies
Table 1
Clinical indications for MRN of the lumbosacral plexus.
To confirm the involvement of the lumbosacral plexus and its extension in patients with tumor diseases
To assess the extent of injuries
To evaluate the lumbosacral plexus in patients with indeterminate MR of the lumbar spine
To exclude presence of masses in patients with unilateral changes in EMG
To exclude lesions in patients with persistent symptoms and normal or indeterminate findings on EMG
To confirm changes of lumbar plexus in patients with confusing clinical findings
To evaluate abnormalities of peripheral nerve branches and associated lesions (e.g., piriformis syndrome, pudendal neuralgia, and meralgia paresthetica)
To plan administration of medications guided by imaging
Note. MRN: magnetic resonance neurography; MR: magnetic resonance; EMG: electromyography.
