The purpose of this study was to assess and compare the reproducibility of trabecular bone structure measurements of the distal radius at 1.5 and 3.0 T magnetic resonance imaging (MRI). Root mean square reproducibility errors ranged from 0.69% to 4.94% at 1.5 T MRI and from 0.38% to 5.80% at 3.0 T MRI. Thus, reproducibility errors of trabecular bone structure measurements are overall in an acceptable range and similar at 1.5 and 3.0 T MRI.
本研究的目的是评估和比较在1.5T和3.0T磁共振成像（MRI）下桡骨远端小梁骨结构测量的可重复性。在1.5T MRI时，均方根可重复性误差范围为0.69%至4.94%；在3.0T MRI时，该误差范围为0.38%至5.80%。因此，小梁骨结构测量的可重复性误差总体处于可接受范围内，且在1.5T和3.0T MRI时相似。
