超声对类风湿关节炎的诊断价值
Prediction and diagnostic value of ultrasound in the diagnosis of rheumatoid arthritis
摘要
Abstract
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<k≤0.8),z=5.415,P=0.000<0.05,which means that two methods (US diagnosis and clinical diagnosis) had high consistency. Conclusion:①Ultrasound has a strong sensitivity to early RA inflammatory activity,and its method is reliable,convenient and safe. The results of the assessment are of predictive value in the diagnosis of disease activity and imaging findings. ②The results of ultrasound assessment are highly similar with the clinical evaluation results. ③In the identification of patients with RA,Doppler ultrasound combined with clinical assessment can more accurately reflect the disease activity of inflammation.关键词
