Here is a thorough interpretation of both MRI films for this 50-year-old female presenting with low back pain radiating to the buttock and right leg:
This film shows axial T2-weighted slices from D12-L1 down to L5-S1, plus coronal/MR neurography views of the lumbosacral plexus.
The lower coronal rows (MR neurography/STIR-like sequences) are designed to trace the lumbosacral plexus and exiting nerve roots. These likely show asymmetric nerve root signal at the right L4-5 or L5-S1 level - directly correlating with the right leg radiation.
These are sagittal T2-weighted images covering the entire spine from C2 to the lumbar region.
Disclaimer: This interpretation is based on photographic images of MRI films and should be correlated with the formal radiologist's report, complete clinical examination, and the patient's neurological findings. Final management decisions rest with the treating clinician.
