Abstract/OtherAbstract:
Background: The Tanner-Whitehouse III (TW3) method, popular for assessing children's bone age, is time-consuming in clinical settings; to depress this, a grouped-TW algorithm (GTA) was developed. Methods: Five hundred and thirty-four left-hand roentgenograms of individuals aged 2-15 years, including 270 training and 264 testing datasets, were evaluated by a senior pediatrician. Next, GTA was used to choose the appropriate candidate of RUS bones and to classify the bones into 3 groups by data mining. In group 1, composed of the maturity pattern of the radius and the middle phalanges of the third and fifth digits, 3 weights were obtained by data mining yielded a result similar to that of TW3. Subsequently, the new bone-age assessment tables were constructed for males and females by linear regression and fuzzy logic. In addition, the Bland-Altman plot was utilized to compare accuracy among the GTA, the Greulich-Pyle (GP), and TW3 method. Results: The relative accuracy between the GTA and the TW3 was 96.2% in males and 95% in females, with an error of 1 year and that between the assessment results of the GP and TW3 was about 87%, with an error of 1 year; however, even if the 3 weighs were not optimally processed, GTA yielded a marginal result with an accuracy of 78.2% in males and 79.6% in females. Conclusions: GTA can efficiently depress the complexity of the TW3 method, while maintaining almost the same accuracy. The relative accuracy between the assessment results of GTA and GP can also be marginal.
