21 patients with rheumatoid arthritis of the wrist diagnosed according to the criteria of the American Rheumatism Association were examined by dynamic MRT before and after the i.v. injection of Gd-DTPA (0.1 mmol/kg). The results were correlated with the clinical and radiological findings. The increased signal intensity of the pannus was 1.17 +/- 0.45%/sec and this differed significantly (p < 0.001) from bone marrow (0.16 +/- 0.11%/sec) and from muscle (0.25 +/- 0.16%/sec). Blood sedimentation rate correlated with the gradient of synovial proliferation (p < 0.05). There were no further statistically significant correlations between the clinical, radiological and MRT findings and the change in signal intensity from synovial proliferation as shown by dynamic MRT.
根据美国风湿病协会的标准诊断为腕部类风湿性关节炎的21例患者，在静脉注射钆喷酸葡胺（0.1 mmol/kg）前后接受了动态磁共振成像（MRT）检查。结果与临床和放射学检查结果相关。血管翳的信号强度增加率为1.17±0.45%/秒，这与骨髓（0.16±0.11%/秒）和肌肉（0.25±0.16%/秒）有显著差异（p<0.001）。血沉与滑膜增殖梯度相关（p<0.05）。动态MRT显示，临床、放射学和MRT检查结果与滑膜增殖信号强度变化之间没有进一步的统计学显著相关性。
