Objective:To observe the changes of Doppler ultrasound in patients with rheumatoid arthritis (RA),and to evaluate the predictive value of Doppler ultrasound parameters in the joint inflammation. Methods:We performed a retrospective analysis of 54 cases of suspected patients with RA,using high frequency ultrasound scanning metacarpophalangeal joints,wrists joints, proximal interphalangeal joint,double ankle,knee joints,evaluated the synovial thickness,joint effusion,blood flow signals and the degree of bone erosion. Results:1188 joints of 54 cases were scaned. Statistics of the joints of the lesions:MCP 87/432 (20%), PIP 76/432 (17.6%),wrists joints 61/108 (56%),double ankle 50/108 (46%),double knee joints 66/108 (61%). US examina-tion showed 37 cases of RA,17 cases of non-RA. There were 4 cases of US examination showed no obvious RA signs,but the clinical diagnosis was RA. The clinical diagnosis was 39 cases of RA,15 cases of non-RA. The sensitivity of RA was 89.7%(35/39),specificity was 73.3% (11/15),RA forecast value 94.5% (35/37),non-RA forecast value 76.5% (13/17). The compara-tive analysis of US diagnosis and clinical diagnosis showed:Kappa=0.734 (0.7展开▼
