Comparison of the diagnostic value of musculoskeletal ultrasound and MRI in early rheumatoid arthritis

目的比较肌肉骨骼超声检查与MRI检查对早期类风湿性关节炎的诊断价值。方法选取2019年1月至2021年6月景德镇市第二人民医院收治的30例疑似类风湿性关节炎患者作为研究对象,均行肌肉骨骼超声及MRI检查。比较肌肉骨骼超声与MRI检查的检出率,以内风湿因子检测结果为金标准,分析两种检查方法的诊断效能。结果两种检查方式超声检查检出率比较差异无统计学意义。肌肉骨骼超声检查的诊断灵敏度、准确度均高于MRI检查,差异有统计学意义(P<0.05),两种检查方法的诊断特异度、阳性预测值、阴性预测值比较差异无统计学意义。结论与MRI检查相比,肌肉骨骼超声检查对早期类风湿性关节炎的检出率更高,且具有较高的灵敏度、准确度,临床可将其作为辅助诊断方式。

Objective To compare the diagnostic value of musculoskeletal ultrasound and MRI in early rheumatoid arthritis.Methods 30 sus-pected rheumatoid arthritis patients admitted to the Second People's Hospital of Jingdezhen City from January 2019 to June 2021 were selected as the study subjects,all patients underwent musculoskeletal ultrasound and MRI examination detection.The detection rates of the two methods were compared,and the results of internal rheumatic factor detection were used as the gold standard to analyze the diagnostic efficacy of the two methods.Results There was no significant difference in the detection rate of ultrasonography between the two methods.The diagnostic sensitivity and accura-cy of musculoskeletal ultrasound examination were higher than those of MRI examination,and the differences were statistically significant(P<0.05),there were no statistically significant differences in the diagnostic specificity,positive predictive value,and negative predictive value between the two examination methods.Conclusion Compared with MRI examination,musculoskeletal ultrasound examination has higher detection rate for early rheumatoid arthritis,and has higher sensitivity and accuracy,which can be used as an auxiliary diagnostic method in clinical practice.
