This T2 star weighted (T2W*) axial gradient recalled echo image is poor, and was scored Grade 2 in quality but there is clearly a right lateral disc protrusion which is of grade 2 severity. The examination was scored 4 (certain) in confidence of diagnosis.

Increased signal indicating the myelomalacia within the cord is also seen. (b) T2 star weighted (T2W*) axial image through neural foramen clearly shows internal structure of the spinal cord and the exiting nerve roots.
