Case Discussion

Small (easily missable) focal foraminal and subarticular disc prolapse.

The MRI study includes an axial T2 3D volume sequence, offering a higher resolution sequence to enable more refined assessment of the nerve roots, which is particularly useful in this case where the disc pathology is small, subtle and in a confined anatomical space.
