MRI is the imaging study of choice in evaluating possible discitis due to its high sensitivity and ability to define associated complications, such as epidural and paraspinous abscess, and should be performed if discitis is suspected even if plain films and CT are non-diagnostic.

Does discitis show on MRI?

Though blood tests may be considered during diagnosis, the most accurate and commonly used diagnostic tool to confirm discitis is magnetic resonance imaging (MRI), which will show an infection if it exists.

Can MRI detect spinal infection?

MRI with and without gadolinium contrast enhancement has become the gold standard in identifying spinal infection and assessing the neural elements. MRI allows for visualization of the soft tissues that include the nerves, spinal cord, and paraspinal muscles, and adjacent soft tissue around the spinal column.
