The current study aims to assess the feasibility of porosity index (PI) measurements derived from ultra-short echo time (UTE) MRI technology in the femoral neck and to further investigate its latent associations with age, gender, body mass index (BMI) and tibial PI. It was concluded that cortical PI measured by UTE MRI sequence can be applied in femoral neck and cannot be replaced by tibial measurement. Femoral neck and tibial PI were observed to correlate with age and BMI , which worth further study.
