MR evaluation of tuberculous spondylitis.

A total of 29 proven tuberculous spondylitis patients underwent MR studies. Gd-DTPA enhancement was performed in 10 patients. Contiguous 2 vertebral involvement, subligamental spread of paraspinal abscesses and cord indentation were observed in 93% of the cases. Destruction of the vertebral body occurred in 76%. Intermediate or low T1 signal intensity and high T2 signal intensity were observed by MR. A combination of these characteristic findings strongly suggests the diagnosis of tuberculous spondylitis. Gd-DTPA administration did not facilitate diagnosis. MR examination should be considered as the main imaging modality for patients with suspected tuberculous spondylitis.
