Results
The ratio of thoracic and lumbar spine lesions was equal (The site of lesion Table 1).
Bone destruction was the most frequent feature of tuberculous spondylitis. The results of detection of bone destruction on the DT appeared to be higher than DR and were similar to CT: DR 70%,
DT 100%,
CT 100%.
Small sequestrum formation was detected in 30% cases by DT and CT,
but was not observed on radiography.
Digital tomosynthesis allowed to accurately detect a paravertebral abscess and its length (67%),
as compared to just 33% with DR.
Also, it enabled detecting destruction of the cortical layer of vertebrae on the lateral surface under the spine ligament, and it was detected with the polysegmental lesion (Ratios of detection spondylitis feature of DR, DT,
CT,
MRI Table 2).
Radiation dose levels of DT compatible with DR and significantly lower than of CT (The radiation dose of DR,
DT,
CT Table 3).
Normal appearance of the spine was shown on DT images (Fig.3,4).
The spatial resolution of the image in the plane of the cut at tomosynthesis is higher than CT (Fig.5).
Spondylitis images are shown (Fig.6,7,8).
Limitations: the DT images of the thoracic spine were more precise and diagnostically informative,
as opposed to the image of the lumbar spine.
Obviously,
this is due to the need to select and optimize scan modes properly (kV,
mAs).
