ObjectiveTo study the clinical value of ultrasound in the diagnosis of gouty arthritis (GA). MethodsA total of 120 GA patients were selected as the study group, and 100 other diseases patients with similar symptoms were selected as the control group during the same period. Both groups received ultrasound examination, and the condition of the joints involvement and the ultrasonic manifestations of the joint lesions were compared between the two groups; meanwhile, the study group was divided into acute GA group and chronic GA group, and the blood flow in and around the synovium of joint were observed in the two groups. ResultsThere were no statistically significant differences in the shoulder joint, knee joint, ankle joint, wrist joint and the first metatarsophalangeal joint involvement between the study group and the control group (all P＞0.05). There were no statistically significant differences in the incidence of bone erosion, hyperechoic points of intra-articular and soft tissue swelling between the study group and the control group (all P＞0.05); however, the incidences of gout stone, hyperechoic points in the surrounding tendons and parallel lines in the study group were significantly higher than those in the control group (all P＜0.05). The level of blood flow classification and detection rate of blood flow signal in the acute GA group were significantly higher than those in the chronic GA group (all P＜0.05). ConclusionUltrasound diagnosis of GA patients can observe the gout stone, parallel lines, hyperechoic points in the surrounding tendons and other imaging features; meanwhile, color Doppler blood flow signal changes can be used to provide the objective and scientific basis for clinical diagnosis of disease activity.
