Direct magnificaiton of the hands of 44 patients on maintenance hemodialysis showed that the earliest unequivocal changes of renal osteodystrophy occur in the tufts. Some workers made a similar observation, but no previous objective study confirmed or refuted the sensitivity of the tufts in the diagnosis of renal osteodystrophy. The macroradiograph is consistently reproducible and serves as an excellent visual record of subtle changes.
对44例维持性血液透析患者手部的直接放大检查显示，肾性骨营养不良最早明确的变化出现在指端。一些研究者有过类似观察，但此前没有客观研究证实或反驳指端在肾性骨营养不良诊断中的敏感性。放大X线片可始终如一地重复拍摄，并能很好地直观记录细微变化。
