Advanced imaging modalities, such as MR imaging or ultrasonography (US), are useful in evaluating disease activity and therapeutic outcome of rheumatoid arthritis (RA). MR imaging can demonstrate bone erosion and edema, which are important in predicting structural articular damage. MR findings are nonspecific but can be helpful in diagnosing RA in its early stage. US can access relatively easily to multiple joints, and power Doppler US allows to visualize the vascularity of synovium. Standardization of imaging and analysis procedures are needed for clinical application of these imaging modalities.
先进的成像方式，如磁共振成像（MR成像）或超声检查（US），在评估类风湿性关节炎（RA）的疾病活动和治疗效果方面很有用。MR成像可以显示骨侵蚀和水肿，这对预测关节结构损伤很重要。MR表现是非特异性的，但有助于在RA早期进行诊断。US可以相对容易地检查多个关节，能量多普勒超声可以显示滑膜的血管情况。这些成像方式在临床应用中需要成像和分析程序的标准化。
