Objective:
To assess the magnetic resonance (MR) imaging features differentiating tuberculous spondylitis from pyogenic spondylitis.
Methods:
MR imaging findings in 10 patients with tuberculous spondylitis were retrospectively compared with those of 13 patients with pyogenic spondylitis.
Results:
There were significant differences in imaging criteria (paraspinal abnormal signal, paraspinal or intraspinal abscess, thoracic spine involvement, and abnormal signal around the facet joint).
Conclusions:
MR imaging is a very useful technique for differentiation of tuberculous spondylitis from pyogenic spondylitis.
