“…7 More recently, molecular imaging methods, such as positron emission tomography (PET/CT) and single photon emission computed tomography (SPECT), have been used to diagnose, characterize, and monitor the activity of inflammatory diseases, such as RA. [7][8][9] For example, (19)F-fl uorodeoxyglucose PET/CT accurately detects infl ammatory activity in large joints of patients with RA, and may be helpful for the early assessment of RA extent. 7 Although the real role of those new techniques in the investigation of RA has not been established, they hold great promise, and, in the future, may play a more critical role in the diagnosis and assessment of disease activity.…”
