Measurement and analysis of objective indicators of ossification development in MRI of knee joint

Motivation: Adolescents have high sensitivity to X-ray, and MRI has the advantage of non-radiation, which has not been perfected in the assessment of adolescent bone age. Goal(s): To analyze the predictive value of MRI ossification development of knee joint with gender and age. Approach: The indexes representing epiphyseal development of distal femur and proximal tibia were selected for measurement, and the differences of epiphyseal development of distal femur and proximal tibia between different gender and different age groups were explored. Results: Males performed better on the distal femur and females on the proximal tibia for age prediction, which could be evaluated separately if necessary. Impact: The objective indicators of ossification development in MRI of knee joint have certain predictive value with gender and age, which helps to evaluate bone age objectively and accurately, and provides a new idea for epiphysis evaluation
