Aims and objectives
Radiography of the spine in two projections for a long time remained the basic method of diagnosis of spondylitis because it's easy to perform and has a low-cost profile.
However, because of the low sensitivity and some physical limitations of the method,
it was replaced by the cross-sectional imaging methods of diagnosis: CT and MRI,
with high sensitivity and specificity.
CT is preferably used for detection bone destruction and sequestrum formations.
But the disadvantage of CT remains a large radiation dose level,
which equals 5-10 mSv per one anatomical part of the spine.
That requires some limitations for frequent use to control the effectiveness of treatment of spondylitis.
MRI is preferably used for evaluation of bone marrow,
soft tissue and cord, yet it still remains expensive.
Digital tomosynthesis (DT) is a new promising method of X-ray diagnostics for performing with high-resolution limited-angle tomography. It suggests performing short-pulsed exposures in one tube pass and reconstructs hundreds of longitudinal sections of the examination object.
There are studies about multiple options of tomosynthesis clinical application.
For instance,
it can be used for breast and chest examination.
Today,
the focus of tomosynthesis application is on musculoskeletal system pathologies.
The aim of our research to study possibilities of digital tomosynthesis for evaluation of spine damage in patients with spondylitis.
