A chest X-ray can predict the risk of osteoporosis! A 44-year-old man had no risk factors for osteoporosis. Through AI osteoporosis screening and chest X-ray, Sanzong accurately predicted that he was in a high-risk group for osteoporosis. Fortunately, he was detected early and treated, thus avoiding fracture and disability.
FRAX risk factors predict osteoporosis in young patients and are easily overlooked

Fang Wenhui, director of the Department of Family Medicine at the Tri-Service General Hospital, pointed out that traditional osteoporosis screening uses FRAX scores, based on age, gender, weight, height, fracture history, parental fracture history, rheumatoid arthritis history, smoking habits, and whether steroids are used. Medications, a history of secondary osteoporosis, and drinking habits are used to calculate the risk of bone loss and fractures in the next 10 years; however, it is easy to overlook groups without known FRAX risk factors, especially young groups.
To this end, the No. 3 research team developed AI osteoporosis screening, which used chest The examination found that 86% were osteoporosis and 13% were osteoporosis, with an accuracy rate of 90%. The results have been published in the Journal of Medical Systems.
Fang Wenhui said that one of the 44-year-old men who participated in the AI osteoporosis screening was diagnosed with osteoporosis. The subsequent DXA examination determined that the bone density of the lumbar spine was -2.8, and the hip joint was -2.5 and -2.4. The osteoporosis screening model is especially suitable for young people who do not have osteoporosis risk factors. Through early screening, high-risk groups for osteoporosis can be detected and early interventional treatment, such as calcium supplementation, vitamin D3 or osteoporosis drugs, can prevent the occurrence of fractures.

AI interprets thoracic spine X-rays to accurately predict the risk of osteoporosis
Why can chest X-ray accurately predict groups at high risk of osteoporosis? Fang Wenhui explained that AI can further predict the bone density of the lumbar spine and hip joint from the ratio of bone and soft tissue in the thoracic spine image. However, if you have suffered from pneumonia or pulmonary hydration, the accuracy of the prediction may be reduced.
Fang Wenhui added that the current diagnosis of osteoporosis is still based on DXA examination, which has the advantage of low radiation dose. It costs about 700 or 800 yuan at one’s own expense, while a chest X-ray costs about 200 or 300 yuan, but the radiation dose is 10 times higher. Chest X-ray replaces DXA examination. Patients who have received chest X-ray examination in the future can receive further treatment through computer prompts when visiting other departments. The doctor will inform the patient.
