MSCT and MRI in the early diagnosis of tuberculous spondylitis

Abstract

The possibilities of MSCT and MRI spine research were analyzwd in 44 patients with tuberculous spondylitis in order to increase the effectiveness of its diagnosis in the early stages of the development of the process. For the retroactive analysis, the group was grouped with 14 (31.8%) of the group, who were buried at the back of the spondytic stage with negative results or the results of the spondylographic system. The productive form of tuberculous spondylitis was observed in 43,2 %, exudative-caseous – in 56,8 % of cases. Defeat of the thoracic department was noted in 61,4%, lumbar – at 38,6 %. It has been established that in the initial stages of the development of tuberculous spondylitis only the MRI study, which allows to determine the diffuse swelling of the bone marrow with the presence of an increased MR signal on T2w, STIR, is low on T1w; changes in the structure of the intervertebral disc in the form of an abnormal increase in the MR signal on T2w, STIR, the presence of intradisk abscess, minimal paravertebral / epidural fatty tissue edema, muscle even in normal anatomical sizes, small interstitial or epidural abscesses, thickening and edema of the spine longitudinal bone , especially with contrast intravenous enhancement. Therefore, in case of suspicion by clinicians the presence of inflammatory process of the spine MRI can be considered a method of choice.
