Abstract

Abstract:

Objective

To compare the computed tomography (CT) and nuclear magnetic resonance imaging (MRI) manifestation in patients with Bacillus spondylitis.

Methods

Total of 38 cases with spondylitis confirmed by surgery, Bacillus agglutination test and clinical follow-up were enrolled in our study, retrospectively. CT and MRI images were analyzed by two professional doctors. Statistical analysis was carried out by SPSS 17.0 software.

Results

The characteristics of CT and MRI in Bacillus Spondylitis were bone destruction of the vertebral body, with bone hyperplasia, no sequestrum formation, no intervertebral space stenosis. MRI in diagnosis of paravertebral and waist muscle abscess (24 cases), intraspinal abscess (18 cases), back soft tissue swelling (26 cases) was more accurate than CT (4 case, 2cases, 2cases ) , with significant differences (F = 2.53, P = 0.02; χ² = 5.52, P = 0.04, F = 3.92, P < 0.001). MRI enhanced scanning could point out the area of bone destruction and vertebral abscess.

Conlusions

MRI could show the range of abscess, abnormal signal in the spinal canal and the soft tissue of the back of the lumbar more clearly than CT for patients with Bacillus spondylitis.

Key words: Bacillus Spondylitis, Imaging manifestation, Computed tomography (CT), Nuclear magnetic resonance imaging
