  • Figure 1
    Sagittal T1, T2, and fat suppressed T2 of lumbar spine
     

    Essentially normal sagittal T1, subtle low signal between L4 and L5 spinous processes and early osteophyte formation on the undersuface of the L4 posterior process.

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    T2 high signal intensity changes are evident between the L4 and L5 spinous processes.

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    T2 high signal between the posterior processes of L4 and L5. Fat suppresion helps to identify the inflamed region.

  • Figure 2
    MRI axial
     

    Axial T2 slice at level of clinical interest Subtle area of high signal in the midline posterior to the spinous process is the region of abnormality identified on Fig 1a-c

     
    Area of Interest: Musculoskeletal soft tissue; Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    Axial T1 at level of clinical interest. Matching slice level from the T2 weighted sequence, note the now corresponding T1 low signal.

     
    Area of Interest: Musculoskeletal soft tissue; Musculoskeletal spine; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 3
    Fluoroscopic bursal injection
     

    Lateral view of the interspace between the posterior processes of L4-L5 demonstrates contained contrast filling of a bursa, this image was obtained just prior to steriod injection.

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: Fluoroscopy; Procedure: Contrast agent-other; Special Focus: Inflammation;

    AP view of the interspace between the posterior processes of L4-L5 demonstrates contained contrast filling of a bursa, this image was obtained just prior to steriod injection.
