| Osteoporosis has always been a major public health disease, with a high rate of disability and mortality, seriously affecting the life health and quality of life of patients, and leading to high medical and health care costs borne by the national medical and health system. At present, bone mineral density is the main index to diagnose osteoporosis and evaluate the risk of fracture. Therefore, accurate measurement of bone mineral density is very important for the early prevention of osteoporosis, but there are many factors affecting the accurate measurement of bone mineral density, and bone marrow fat is a focus of attention now. At present, the means of quantitative analysis of bone marrow fat content and bone mineral density in continuous innovation, and the energy CT as a new technology has the attention of the researchers, therefore, the purpose of this review is to discuss energy CT quantitative analysis of the research progress of bone mineral density and bone marrow fat content, for the follow-up, related research provides a new method for the feasibility of the image. |
