Pediatric endocrinologists at a children's hospital were concerned that bone age readings by radiologists frequently differed from their readings by >1 year.
To compare consistency of bone age readings by endocrinologists vs. radiologists, and the Greulich and Pyle (GP) atlas vs. the recently published Gilsanz and Ratib (GR) digital atlas.
Sixteen radiographs were read by seven radiologists and five endocrinologists, using both the GP and GR atlases. Time to complete all 16 readings was recorded. An intraclass correlation coefficient (ICC) was used to assess the level of agreement between the two disciplines and the use of different atlases.
The ICCs for the seven radiologists and five endocrinologists were both 0.95; the ICC for readings done by GP vs. GR for all raters was 0.96. The number of outlier readings was similar for radiologists and endocrinologists but was higher for GR than for GP. Radiologists spent less time (1.15 min) reading each bone age than endocrinologists (2.4 min).
Under controlled conditions, pediatric endocrinologists and radiologists displayed nearly identical consistencies in reading bone ages. The GR atlas performed similarly to the GP atlas, except for an increased number of outliers, and might be suitable as a replacement for GP.
儿童医院的儿科内分泌医生担心放射科医生的骨龄读数经常与他们的读数相差>1 年。
比较内分泌医生与放射科医生的骨龄读数的一致性，以及 Greulich 和 Pyle (GP) 图谱与最近发布的 Gilsanz 和 Ratib (GR) 数字图谱。
16 张 X 光片由 7 名放射科医生和 5 名内分泌医生使用 GP 和 GR 图谱进行阅读。记录完成所有 16 次阅读所需的时间。使用组内相关系数 (ICC) 评估两个学科之间以及使用不同图谱的一致性水平。
7 名放射科医生和 5 名内分泌医生的 ICC 均为 0.95；所有评分者使用 GP 与 GR 的 ICC 为 0.96。放射科医生和内分泌医生的异常读数数量相似，但 GR 比 GP 高。放射科医生阅读每个骨龄的时间（1.15 分钟）少于内分泌医生（2.4 分钟）。
在受控条件下，儿科内分泌医生和放射科医生在阅读骨龄方面表现出几乎相同的一致性。GR 图谱与 GP 图谱表现相似，只是异常读数的数量增加，可能适合替代 GP。
