ABSTRACT

Objective:

To explore the diagnostic value of high field intensity magnetic resonance imaging(MRI) in the early changes of wrist rheumatoid arthritis(RA).

Methods:

150 patients with joint pain were enrolled in the retrospective analysis. And in these patients, the patients with RA who were diagnosed by using high field intensity MRI were divided into observation group(102 cases), and others were divided into control group (48 cases). The diagnostic value of high field intensity MRI for the early change of wrist RA were further explored and discussed.

Results:

The diagnostic sensitivities of early change, synovial thickening, bone marrow edema, bone erosion, arthroedema and myotenositis of high field intensity MRI for RA were higher than 60%, and the diagnostic specificity of them were higher than 50%, and the diagnostic sensitivity of synovial thickening of these indicators even achieved to 100%. The positive rates of these indicators of observation group was significantly higher than that of control group, respectively (x2=108.147, x2=27.943, x2=50.473, x2=51.549, x2=17.558, P<0.05). And all of synovial thickening, bone marrow edema, bone erosion, arthroedema and myotenositis were the independent influence factors of early diagnosis of wrist RA(OR=9.631, OR=10.114, OR=25.867, OR=26.258, OR=14.027, P<0.05).

Conclusion:

MRI is one of the reliable methods for diagnosing early wrist RA. Synovial thickening, bone marrow edema, bone erosion, joint effusion and tendonitis can be used as the main symptom in diagnosis. And they can be combined with clinical symptom, sign and laboratory examination results to carry out comprehensive judgment for RA of wrist.
