| Objective:To evaluate the effectiveness of ultrasonography in detecting Rheumatoid Arthritis through ultrasonographic image of suprapatellar bursa'fluid,synovium,and femoral condylar cartilage in the knee joints.Methods:The ultrasonographic image of suprapatellar bursa'fluid, synovium and femoral condylar carti 2 lage was compared between people with and without Rheumatoid Arthritis.The changes of suprapatellar bursa'fluid and thickness,color flow grading,RI of synovium and femoral condylar cartilage in the patient with Rheuma 2 toid Arthritis before and after therapy were measured. The correlations between suprapatellar bursa'fluid,thick 2 ness,color flow grading,RI of synovium and CRP(o|¨)ESR were analyzed.Results:The suprapatellar bursa'fluid and synovium in the patients with Rheumatoid Arthritis before treatments were thicker than those without Rheumatoid Arthritis.After treatments for the patients with Rheumatoid Arthritis,the thickness of suprapatellar bursa 'fluid and synovium decreased,the color flow of synovium reduced,whearaus the RI increased.The ESR(o|¨) CRP were correlated with the thickness of suprapatellar bursa'fluid and synovium and color flow grading.Conclusion:Ultrasonography is an auxiliary diagnostic instrument,which can be used in evaluating the therapeutic effect on Rheumatoid Arthritis. |
