Abstract:: Abstract: Objective To discuss the diagnostic value of color Doppler ultrasound in differentially diagnosing gouty arthritis (GA) and osteoarthritis (OA). Methods Fifty patients with GA and 50 patients with OA who were treated in First People’s Hospital of Foshan between December 2014 and December 2017 were selected. Color Doppler ultrasound was applied to exam the first metatarsophalangeal joints in both two groups, and the ultrasound manifestations were analyzed. Results The comparison of joint effusion, synovial thickening, and the classification of synovial blood flow in GA group and OA group didn’t show any statistical differences (P>0.05). However, statistical significance was found in multi-point hyperechoic, double-track sign, and gouty tophi between GA group and OA group (P<0.05). The level of synovial blood flow in patients with GA at acute stage was significantly higher than that in those with GA at chronic stage, with statistical significance (P<0.05). Conclusion Using color Doppler ultrasound to exam the first metatarsophalangeal joint can effectively distinguish GA and OA. Moreover, GA synovial blood flow classification can provide important references for GA assessment, worthy of further clinical promotion.
