To study the ultrasound signs of synovitis and Doppler signs of local inflammation of the knee in rheumatoid arthritis (RA) were examined 32 persons (16 patients with documented diagnosis of rheumatoid arthritis and 16 practically healthy individuals) . B-mode regimen was used to assess anatomical structures of the joint. Spectral Doppler analysis with calculation of resistance index (RI) and pulsatility index, maximum and minimum systolic velocity, medium velocity and diastolic velocity was used for all subjects to determine profile of the blood flow in the exstrasinovial vessels of the knee such as the upper lateral knee artery. Ultrasound indicators were compared with clinical and laboratory data. Significant differences were noted between the main and control groups in the thickness and length of effusion in the joint and the thickness of the synovial membrane (p <0.05). ) Groups significantly differed in the RI obtained using spectral Doppler analysis. In the control group the parameters of RI in the upper lateral knee artery was significantly higher. These results confirm the possibility of using exstrasinovial vessels to assess the vascularization of the knee as a screening method for diagnosing arthritis.
