Introduction
Measuring bone age generally involves radiation exposure. The assessment is typically done using an X-ray of the left hand. By examining the image and comparing it with standard reference images, doctors can determine skeletal age and evaluate the degree of bone development. This procedure is usually performed in a hospital's radiology department. Although there is radiation exposure during the test, it is generally within a safe range and does not cause significant adverse effects on growth, development, or health.
Measuring bone age generally involves radiation, but the radiation dose is usually small.
In clinical practice, bone age assessment typically uses an X-ray of the left hand. This involves imaging the phalanges, metacarpal bones, and carpal bones—specifically 29 ossification centers. The size and shape of these 29 ossification centers are comprehensively evaluated and compared with standard reference images to determine skeletal age and assess the degree of bone development. Since bone age measurement is performed in a hospital radiology department, there is generally some exposure to radiation; however, it is typically within safe limits and does not cause significant adverse effects on growth, development, or health.
Because different physicians may interpret bone age images differently, it is recommended to visit an orthopedic department at a reputable medical institution where a specialized doctor can accurately assess bone age.
