MRI study of cervical spine shows mild loss of normal cervical lordosis.
Spinal cord and exiting nerve roots normal.
MRI FOR BRACHIAL PELXUS performed with Coronal STIR, Cor FIESTA, Axial T2, STIR and MR Myelography.

This axial T2w MRI study of Brachial plexus shows:
T2 hyper intensity of fluid between right side anterior and middle scalene muscles attributed to odema / hematoma, the region corresponds to the course of Brachial plexus. Injury to right side Brachial plexus possible here.

Compression fracture with cord contusion

A young male with history of road traffic accident. 

MRI lumbar spine
Sagittal STIR and T2w image with axial T2w image at the level of L1 shows: 
L1 compression fracture with hyper intense marrow odema on STIR. 
Retropulsion of posterior fragment causing canal stenosis, cord compression.
A focal T2 hyper intense cord contusion and cord odema.
L5 show a superior sub chondral collapse with hyper intense marrow odema on STIR. 
Adjacent intervening discs are uninvolved.
