摘要: 探究动态增强磁共振成像(DCE-MRI)检查五项参数与类风湿关节炎(RA)患者疾病活动度的相关性及联合预测近期预后的临床价值。选取105例RA患者作为研究对象,均根据治疗6个月后治疗反应情况分为预后良好组(80例)与预后不良组(25例)。结果发现,DCE-MRI检查参数RE、MRE、ME、Slopemax、AUC随疾病活动度增加呈升高趋势,与疾病活动度呈正相关(r=0.759、0.803、0.763、0.666、0.724,P<0.05),与近期预后显著相关;且DCE-MRI检查五项参数联合预测近期预后的AUC为0.937,95%CI为0.872~0.975,P<0.001,敏感度为80.00%,特异度为95.00%,显著优于单独预测。提示采用DCE-MRI检查五项参数可作为临床评估RA病情程度、预测近期预后的可靠手段,为临床提供科学循证依据。

Abstract: The correlation between the five parameters of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) and the disease activity of patients with rheumatoid arthritis (RA) and the clinical value of joint prediction of short-term prognosis. A total of 105 RA patients were selected as the research objects. They were divided into a good prognosis group (80 cases) and a poor prognosis group (25 cases) according to the treatment response after 6 months of treatment. The results showed that RE, MRE, ME, Slopemax and AUC in DCE-MRI showed an increasing trend with the increase of disease activity, and were positively correlated with disease activity (r=0.759, 0.803, 0.763, 0.666, 0.724, P<0.05). Significantly related to the short-term prognosis. The five parameters of DCE-MRI examination combined predict the short-term prognosis AUC of 0.937, 95%CI of 0.872-0.975, P<0.001, sensitivity of 80.00%, specificity of 95.00%, significantly better than individual forecast.It is suggested that the five parameters of DCE-MRI examination can be used as a reliable method to clinically evaluate the severity of RA and predict the short-term prognosis, and provide a scientific evidence-based basis for the clinic.
