Aims and objectives

Digital tomosynthesis (DT) is a perspective method for diagnosing the pathology of the skeletal system, especially in children. Tomosynthesis provides slices of limbs in standard projections, eliminating the mad overlays, which lead to difficulties in diagnosing with conventional radiography. The diagnostic images obtained in this mode are close in quality to computed tomograms, which makes it possible to evaluate the bone structure and carry out a differential diagnosis of the pathology at a low radiation dose. Aims and objectives: evaluation of the possibilities of digital...

Methods and materials

We were analyzed the examination of 18 children limbs: 8 (44.5%) of them were with dysplastic changes, 4 (22.2%) of them were with tumors and 6 (33.3%) of them - with inflammatory bone changes. The average age of patients was 10.6 ± 4.2 years. The examination was performed on a domestic digital X-ray diagnostic complex with a digital tomosynthesis regimen after performing digital radiography. In 12 (66,7%) patients were additionally performed MSCT.

Results

After further examination, preliminary conclusions were confirmed in 72.2% of cases. DT allowed to clarify the X-ray picture of the pathology in 72,2% of cases. In 4 (22,2%) children the radiological conclusion was changed: in one patient - from the norm to osteoid osteoma (Fig. 1), in other - from osteoid osteoma to pathological restructuring (Fig. 2); in the 3rd case (the boy was engaged in the team of the Paralympic team and had heavy loads) - from non-ossifying fibroma to enchondroma (Fig. 3), in...

Conclusion

Digital tomosynthesis can be a low-dose alternative to computed tomography in children at the initial stage of diagnostic. Its allows to obtain more accurate information about the bone structure in 40% of cases and monitoring the treatment of children without an extra radiation dose.
