Abstract:
Objective To explore the value of ultrasound on the early bone erosion of finger joint in patients with rheumatoid arthritis (RA).Methods Sixty-three cases of RA patients (patients group) with 486 finger joints was examined by high-frequency ultrasound,X-ray films and MRI,and compared with 20 controls (control group).Results The ultrasound results were significant difference between two groups (P<0.01).The positive rate was 84.2%(409/486) in high-frequency ultrasound,and 56.2%(273/486) in X-ray films,there was significant difference between the two (P < 0.05 ).The positive rate by high-frequency ultrasound was 63.8% (136/213) in X-ray check-negative patients,and 68.1% (145/213) by MRI.The results of the MRI contrast sensitivity of 97.6%,specificity of 75%,accuracy of 96.5% by high-frequency ultrasound.Conclusion The high-frequency ultrasound on the X-ray check-negative patients with rheumatoid hand early joint bone erosion have some diagnostic value.
