Fifteen drivers with LBP were examined by MRI of the lumbar spine (L1–S2) in sagittal plane by 1 T imager (Siemens Magnetom Impact Expert) with TSE T1, T2 and STIR. techniques and in axial plane (L3–S1) with T2 tech- nique. The slice thickness was 4 mm, the field of view
in sagittal 140 mm × 280 mm (126 × 256 pixels) and axial
188 mm × 250 mm (223 × 512 pixels) images. The earliest
sign of disc degeneration was stated as decrease in signal
density. The annular rupture was stated to be a peripheral light signal.
