In 84% of cases, VFs are not reported on chest CT (CCT), which calls for the development of an artificial intelligence-based (AI) assistant that would help radiology specialists to improve the diagnosis of osteoporosis complications and prevent new LE fractures.<jats:bold>AIMS<\/jats:bold>: To develop an AI model for automated diagnosis of compression fractures of the thoracic spine based on chest CT images.<jats:bold>MATERIALS AND METHODS<\/jats:bold>: Between September 2019 and May 2020 the authors performed a retrospective sampling study of \u0421\u0421\u0422 images. The 160 of results were selected and anonymized. The data was labeled by seven readers. Using the morphometric analysis, the investigators received the following metric data: ventral, medial and dorsal dimensions. This was followed by a semiquantitative assessment of VFs degree. The data was used to develop the Comprise-G AI mode based on CNN, which subsequently measured the size of the vertebral bodies and then calculates the compression degree. The model was evaluated with the ROC curve analysis and by calculating sensitivity and specificity values.<jats:bold>RESULTS<\/jats:bold>: Formed data consist of 160 patients (a training group - 100 patients; a test group - 60 patients). The total of 2,066 vertebrae was annotated. When detecting Grade 2 and 3 maximum VFs in patients the Comprise-G model demonstrated sensitivity - 90,7%, specificity - 90,7%, AUC ROC - 0.974 on the 5-FOLD cross-validation data of the training dataset; on the test data - sensitivity - 83,2%, specificity - 90,0%, AUC ROC - 0.956; in vertebrae demonstrated sensitivity - 91,5%, specificity - 95,2%, AUC ROC - 0.981 on the cross-validation data; for the test data sensitivity - 79,3%, specificity - 98,7%, AUC ROC - 0.978.<jats:bold>CONCLUSIONS<\/jats:bold>: The Comprise-G model demonstrated high diagnostic capabilities in detecting the VFs on CCT images and can be recommended for further validation.<\/jats:p>","DOI":"10.14341\/probl12605","type":"journal-article","created":{"date-parts":[[2020,12,28]],"date-time":"2020-12-28T10:57:25Z","timestamp":1609153045000},"page":"48-60","update-policy":"https:\/\/doi.org\/10.14341\/crossmarkpolicy2018","source":"Crossref","is-referenced-by-count":8,"title":["Artificial intelligence for diagnosis of vertebral compression fractures using a morphometric analysis model, based on convolutional neural networks"],"prefix":"10.14341","volume":"66","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1694-4682","authenticated-orcid":true,"given":"A.
