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 parameters and modes (fig.
3).
The CBCT evidence were compared with the data of magnetic resonance tomography (MRI) which has been performed on Centauri MPF 3000 (XinAO MDT,
China),
digital microfocus radiography (DMFR) with direct multiple images magnification (х3),
which has been carried out on X-ray unit Pardus (Russia) and standard radiography (SR) – on X-ray unit KRD-SM 50/125-1 (Spektrup,
Italy,
Japan,
France) – of the knee joints in 40 % (n = 12),
50 % (n = 15) and 50 % (n = 15) of the cases respectively.
The CBCT data were correlated also with the findings of multislice computed tomography (MSCT),
which have been conducted on Brilliance 64 (Philips,
Holland),
to 30 patients with the similar pathology (fig.
4).
