Schematic diagram showing the peri-neural fat surrounding the nerve root in grade zero stenosis. Grade one (mild) stenosis is showing partial loss of the peri-neural fat whereas grade two (moderate) and grade three (severe) stenosis are showing circumferential loss of peri-neural fat. The T1W sagittal MRI image is showing a partial loss of the epidural fat surrounding the nerve root in the left neuroforamen at L4/L5
