Sixteen outpatients with rheumatoid arthritis took part in a placebo controlled double-blind crossover study. In addition to conventional measurements, a radioactive index was measured using a gamma camera that indicated a radioactive count over the measured joints and a comparable area of normal adjacent bone. This index showed poor correlation with other conventional measurements of change in the clinical trial.
16名类风湿性关节炎门诊患者参与了一项安慰剂对照双盲交叉研究。除了常规测量外，还使用伽马相机测量了一个放射性指数，该指数显示了测量关节及相邻正常骨的可比区域的放射性计数。在该临床试验中，这一指数与其他常规变化测量指标的相关性较差。
