Aims and objectives
Injuries and diseases of musculoskeletal system occupy the 4th place in the overall structure of morbidity in the world.
They are located on the 2nd place among all the causes of temporary disability [1].
To characterize a bone structure or to detect its changes the diagnosis algorithm is limited mostly by a standard radiography,
as a technique of the «first step» in such cases.
Along with this the main trend in the development of modern radiology in osteology is a new class of a contemporary...
Methods and materials
In total,
30 patients,
among them 8 men and 2 women,
at the age from 14 to 46 years old with posttraumatic changes (n = 14) and some kinds of diseases (n = 16) of knee joint were examined on modern specialized CBCT-scanner – NewTom 5G (QR S.r.l.,
Italy),
completed with tomographic table (fig.
2).
The CBCT-methodology (the individual scanning settings) of the knee joint study has been elaborated for the study unification: the most comfortable positioning of the patient with special nonopaque tools,
technical...
Results
The received CBCT-images of the knee joints were characterized by the detailed mapping of the bone structure with the accurate differentiation and direction of bone trabeculae.
It has become possible to trace its orientation (fig.
5).During the comparative analysis it has been found that visualization of the bone structure on the CBCT-images was comparable or even exceeded MSCT and DMFR with direct multiple images magnification (х3),
but it was not defined on SR.
In addition,
small bone fragments and areas of pathological alteration of bone...
Conclusion
During the detailed analysis of the knee joints CBCT-images the following capabilities of the technique were identified:
- CBCT could be applied as a priority method when evaluating small (less than 1 mm) areas of bone tissue pathological rearranging and posttraumatic changes,
where summational effects pronounced mostly on SR;
- CBCT allows assessing a state of dense soft tissue structures;
- CBCT-images stand out with the lack of significant artifacts from high density materials.
It does not reduce the quality of CBCT-tomograms and do not...
