Figure 1: (a) Normal lumbar MRI. (A1) Sagittal midline 500/17 (TR ms/TE ms), 4 mm thick image of the lower lumbar spine. (A2) Sagittal midline 2000/90 (TR ms/TE ms), 4 mm thick image. (b) Type 1 change in a male with low back pain. Hypointense T1-weighted image, hyperintense T2-weighted image. (B1) Sagittal midline 500/17 (TR msec/TE ms), 4 mm thick image of the lower lumbar spine. There is decreased signal intensity of the inferior aspect of L4 as well as the superior aspect of L5. (B2) Sagittal midline 2000/90 (TR ms/TE ms), 4 mm thick image. There is increased signal of the adjacent portions of the L4 and L5 vertebral bodies. (c) Type 2 change in a male with low back pain. Hyperintense T1-weighted and T2-weighted images. (C1) Sagittal midline 500/17 (TR ms/TE ms), 4 mm thick image through the lower lumbar spine. There is increased signal of the adjacent portions of the L4 and L5 vertebral bodies. (C2) Sagittal midline 2000/90 (TR msec/TE msec), 4 mm thick image. There is increased signal of the adjacent portions of the L4 and L5 vertebral bodies. (d) Type 3 change in a male with low back pain. Hypointense T1-weighted and T2-weighted images. (D1) Sagittal midline 500/17 (TR ms/TE ms), 4 mm thick image through the lower lumbar spine. There is decreased signal of the adjacent portions of the L1 and L2 vertebral bodies (white arrow). There is increased signal of the adjacent portions of the L5 and S1 vertebral bodies (Type 2 change – black arrow). (D2) Sagittal midline 2000/90 (TR msec/TE ms), 4-mm-thick image. There is decreased signal of the adjacent portions of the L1 and L2 vertebral bodies (white arrow). There is increased signal of the adjacent portions of the L5 and S1 vertebral bodies (Type 2 change – black arrow). MRI: Magnetic resonance imaging
