Description
Su Wu, James Francis Griffith, João Dourado, and Lai Shan Tam ask whether wrist scans for rheumatoid arthritis can skip the injected contrast dye. The standard scan uses dye to reveal inflammation of the joint lining, but the dye adds cost, time, and discomfort for patients.
They scanned the sore wrists of dozens of patients three ways and had two radiologists grade the inflammation on each. One dye-free sequence matched the dye scans almost exactly for grading the joint lining. It did, however, overstate inflammation of the tendon sheaths. A second dye-free sequence overstated both. The authors say the matching sequence can reasonably replace the dye scan when the joint lining is the question.
