摘要: 本文探究类风湿关节炎(RA)药物治疗前后动态增强磁共振成像(DCE-MRI)定量参数变化及对骨侵蚀情况的影响。选取112例RA患者,于药物治疗前后行DCE-MRI检查测量定量参数[最大增强(Emax)、最大相对增强(REmax)、相对增强(RE)、最大强化斜率(Slopemax)],比较有反应和无反应患者治疗前后DCE-MRI定量参数、骨侵蚀评分。结果显示,无反应者治疗前、治疗后Emax、REmax、RE、Slopemax均高于有反应者,治疗前后Emax、REmax、RE、Slopemax变化值均低于有反应者(P<0.05)。治疗前后Emax、REmax、RE、Slopemax变化值均与RA患者药物治疗反应性呈正相关(P<0.05)。治疗前Emax、REmax、RE、Slopemax联合预测RA药物治疗反应性为无反应的曲线下面积(AUC)为0.901(95% CI:0.830~0.949)。无反应者治疗前、治疗后骨侵蚀评分均高于有反应者,治疗前后骨侵蚀评分变化值低于有反应者(P<0.05)。治疗前后Emax、REmax、RE、Slopemax变化值均与RA患者骨侵蚀评分变化值呈正相关(P<0.05)。可见,治疗前DCE-MRI定量参数Emax、REmax、RE、Slopemax能预测RA药物治疗反应性,且各参数变化值与骨侵蚀变化情况密切相关。

Abstract: This paper investigated the changes in quantitative parameters of dynamic enhanced magnetic resonance imaging (DCE-MRI) before and after drug treatment for rheumatoid arthritis (RA) and the effects on bone erosion. 112 patients with RA were selected, and quantitative parameters[maximum enhancement (Emax), maximum relative enhancement (REmax), relative enhancement (RE), and slope of maximum enhancement (Slopemax)] were measured by DCE-MRI before and after drug treatment to compare quantitative DCE-MRI parameters and bone erosion scores before and after treatment in patients with and without response. The results showed that Emax, REmax, RE, and Slopemax in non-responders were higher than in responders before and after treatment, and the change values of Emax, REmax, RE, and Slopemax before and after treatment were lower than those of responders (P<0.05). The change values of Emax, REmax, RE, and Slopemax before and after treatment were positively correlated with drug treatment in RA patients(P<0.05). The area under the curve (AUC) of the combination of Emax, REmax, RE, and Slopemax before treatment to predict RA drug treatment responsiveness as non-response was 0.901 (95% CI:0.830-0.949). The bone erosion scores before and after treatment in non-responders were higher than in responders, and the change in bone erosion scores before and after treatment was lower than in responders (P<0.05). The values of Emax, REmax, RE, and Slopemax before and after treatment were positively correlated with the change in bone erosion score in RA patients (P<0.05). It can be seen that the quantitative parameters Emax, REmax, RE, and Slopemax of DCE-MRI before treatment can predict the responsiveness to RA drug treatment, and the change values of each parameter are closely related to the change of bone erosion.
