Abstract:
Objective To investigate the application value of three-dimensional power Doppler ultrasonography(3D-PDU) for synovial disease in patients with rheumatoid arthritis(RA). Methods Forty four patients with RA were divided into active (23 cases) and non-active (21 cases) groups. 3D-PDU was used in the wrists to measure the volume of synovium(V) ,vascular index(VI) in synovium.and Doppler spectrum was used to measure synovial artery peak systolic blood flow velocity(PSV) , end diastolic velocity (EDV) and resistance index(RI). Results There were significant differences of the V [(1. 73 0. 73) cm3] and VI (9. 53 6. 11) in the group of active patients compared to the V [(1. 09 0. 76) cm3 , P = 0. 008] and VI [(3.86 4.99), P = 0.000] in the ones of inactive patients. No differences were found for PSV [(16. 8 6. 29) cm/s vs (13. 5 8. 54) cm/s, P = 0. 282] ,EDV [(5. 51 1.77) cm/s vs (5. 03 2. 76) cm/s, P = 0. 539] and RI (0. 66 0. 07 vs 0. 62 0. 08, P = 0. 095)in the comparison of two groups. Conclusions 3D-PDU in determining RA disease activity in patients with synovial medium has a higher application value, VI can be used as an effective indicator to determine the disease activity.
