摘要:


文题释义:

骨龄:是骨骼年龄的简称,需要借助于骨骼在X射线摄像中的特定图像来确定。通常要拍摄人左手手腕部的X射线片,通过X射线片观察左手掌指骨、腕骨及桡尺骨远端的骨化中心的发育程度来确定骨龄。目前在国内医学和体育领域有3种骨龄评估方法较为广泛应用,分别为Greulich-Pyle图谱法(GP法)、CHN计分法(CHN法)、中华05法。
Greulich-Pyle图谱法:简称GP法,该方法以其研制者Greulich W.W.和Pyle S.I.两位研究专家命名,图谱有58张标准片,其中男子31张标准片,女子27张标准片,临床医生在评估时把患者左手的骨龄片与标准片进行比较,最相近的标准片的骨龄值为患者的骨龄,如无最相近的标准片,将采用插入法,取2张标准片中间值作为患者骨龄。


背景:人工智能骨龄评估已成为研究热点,国内外研究表明人工智能技术在医学影像领域发展迅速,为更准确快速的对骨龄进行评估提供了可能。

目的:探讨人工智能Greulich-Pyle (智能GP)图谱骨龄评估系统与人工专家Greulich-Pyle(专家GP)图谱评估结果的一致性。
方法:骨龄片采样对象为6-15岁儿童青少年,其中男672人,女650人。同一张骨龄片分别用智能GP与专家GP读出骨龄值。智能GP读片结果的准确性采用差值绝对值反映;骨龄结果一致性采用Pearson相关、Bland-Altamn分布图;评估一致性采用Kappa检验。

结果与结论:①智能GP骨龄与专家GP骨龄差值95%置信区间男女总体分别为0.39岁(0.37-0.41岁),0.32岁(0.29-0.34岁),智能GP骨龄与专家GP骨龄差值Bland-Altamn偏差男女分别为(-0.096±0.482)岁,(0.014±0.415)岁;②智能GP骨龄与专家GP骨龄男女相关结果分别为r=0.991,r=0.992,P < 0.000 1;男女所有年龄段差值中位数均在0.5岁之内;Kappa检验值除男子9岁年龄段,其他各年龄段男女均大于0.4,总体Kappa值男女分别为0.603,0.659;③结果表明:在6-15岁儿童青少年范围内,人工智能GP图谱骨龄值与专家评估结果有高度一致性。

Abstract: BACKGROUND: Artificial intelligence-assisted bone age assessment has become a research hotspot. Domestic and foreign studies have shown that the rapid development of artificial intelligence technology in the field of medical imaging provides the possibility of more accurate and rapid assessment of bone age. 
OBJECTIVE: To investigate the consistency between a domestically developed artificial intelligent Greulich-Pyle (GP) bone age assessment system and an expert manually assessed GP (expert GP), and to provide a basis for the feasibility of applying an artificial intelligent GP in clinical practice or in other fields. 
METHODS: Wrist radiographs were sampled from children and adolescents aged 6-15 years, of whom 672 were male and 650 were female. Bone age assessment of the same wrist radiograph was performed using the artificial intelligent GP and the expert GP. The accuracy of the artificial intelligent GP reading results was assessed by the absolute value of the difference. The consistency of the bone age results was assessed by Pearson correlation and Bland-Altamn distribution; and the consistency of the assessment was checked by Kappa test. 
RESULTS AND CONCLUSION: The absolute value of the difference (95% confidence interval) of the difference between artificial intelligent GP and expert GP for male and female was 0.39 years (0.37-0.41 years) and 0.32 years (0.29-0.34 years), respectively. The deviation of Bland-Altamn values for male and female was (-0.096±0.482) years and (0.014±0.415) years, respectively. The correlation results between artificial intelligent GP bone age and expert GP bone age for male and female were r=0.991 and r=0.992, respectively (P < 0.000 1). The median difference between all age groups for male and female was within 0.5 years. Kappa test values were greater than 0.4 for both sexes at all ages except for the 9-year age group for male. Overall Kappa values were 0.603 and 0.659 for male and female respectively. To conclude, there is a high degree of consistency between the artificial intelligence and expert evaluation results of GP bone age values in children and adolescents aged 6-15 years.
