However, as clinical procedures are a subjective assessment, the accuracy depends highly on the doctor\u2019s experience. Motivated by this, a deep learning-based computer-aided diagnosis method was proposed for performing bone age assessment. Inspired by clinical approaches and aimed to reduce expensive manual annotations, informative regions localization based on a complete unsupervised learning method was firstly performed and an image-processing pipeline was proposed. Subsequently, an image model with pre-trained weights as a backbone was utilized to enhance the reliability of prediction. The prediction head was implemented by a Multiple Layer Perceptron with one hidden layer. In compliance with clinical studies, gender information was an additional input to the prediction head by embedded into the feature vector calculated from the backbone model. After the experimental comparison study, the best results showed a mean absolute error of 6.2\u00a0months on the public RSNA dataset and 5.1\u00a0months on the additional dataset using MobileNetV3 as the backbone.<\/jats:p>","DOI":"10.1007\/s40747-021-00376-z","type":"journal-article","created":{"date-parts":[[2021,4,20]],"date-time":"2021-04-20T11:46:33Z","timestamp":1618919193000},"page":"1929-1939","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":46,"title":["A deep learning-based computer-aided diagnosis method of X-ray images for bone age assessment"],"prefix":"10.1007","volume":"8","author":[{"given":"Shaowei","family":"Li","sequence":"first","affiliation":[]},{"given":"Bowen","family":"Liu","sequence":"additional","affiliation":[]},{"given":"Shulian","family":"Li","sequence":"additional","affiliation":[]},{"given":"Xinyu","family":"Zhu","sequence":"additional","affiliation":[]},{"given":"Yang","family":"Yan","sequence":"additional","affiliation":[]},{"given":"Dongxu","family":"Zhang","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2021,4,20]]},"reference":[{"key":"376_CR1","doi-asserted-by":"publisher","first-page":"e0220242","DOI":"10.1371\/journal.pone.0220242","volume":"14","author":"AL Dallora","year":"2019","unstructured":"Dallora AL, Anderberg P, Kvist O, Mendes E, Diaz Ruiz S, Sanmartin Berglund J (2019) Bone age assessment with various machine learning techniques: a systematic literature review and meta-analysis.
