Thermography and its use in diagnosis of active sacroiliac ankylosing spondylitis

The objective of this study was to investigate the value of sacroiliac thermography in the assessment of disease activity in ankylosing spondylitis [AS]. The clinical, laboratory and sacroiliac thermographic indices were done for 27 patients with AS. Clinical disease activity was demonstrated in 13 patients, while the other 14 were inactive. The mean sacroiliac thermographic index was significantly higher in active ankylosing spondylitis group than either the inactive or the control group. Furthermore, significant correlations were observed between the thermographic indices and other parameters of the disease activity
