(A) Sagittal STIR sequence; (B) sagittal T1 weighted sequence with fat saturation after administration of Gd-DTPA. Florid anterior and posterior spondylitis at the L4/5 level (small arrows) and spondylodiscitis at the L2/3 level (large arrow) as depicted by the two techniques. Additionally, there is severe enthesitis of the interspinal ligaments in the T12–L2 region (arrowheads).
