Male patient aged 45 years old presented with low back pain referred to left leg for 6 months. a Sagittal T2WI of lumbar spine showing: L4/L5 heterogeneous, intermediate to hypointense signal, lost nucleus-annulus distinction, moderately decreased disk space (grade 4). L5/S1 heterogeneous, intermediate to hypointense signal, lost nucleus-annulus distinction, moderately decreased disk space (grade 4). Sagittal color coded post processing T2 mapping (b–d) and (e–g) of most degenerated disks L4–5 and L5–S1 respectively , Sagittal post processing ADC mapping (h–j) and (k–m) of same respectively with ROIs placed on nucleus pulposus, annulus fibrosus and entire of the disks and the values tabulated as follows:

  T2 mapping ADC values
NP AF Entire of disk NP AF Entire of disk
L1/L2 101 81 92 1.60 1.73 1.46
L2/L3 100 75 87 1.57 1.89 1.69
L3/L4 108 85 88 1.91 1.71 1.79
