Abstract

Radiation exposure during forensic age estimation is associated with ethical implications. It is important to prevent repetitive radiation exposure when conducting advanced ultrasonography (USG) and magnetic resonance imaging (MRI). The purpose of this study was to investigate the utility of 3.0-T MRI in determining the degree of ossification of the distal femoral and proximal tibial epiphyses in a group of Turkish population. We retrospectively evaluated coronal T2-weighted and turbo spin-echo sequences taken upon MRI of 503 patients (305 males, 198 females; age 10-30 years) using a five-stage method. Intra-and interobserver variations were very low. (Intraobserver reliability was kappa = 0.919 for the distal femoral epiphysis and kappa = 0.961 for the proximal tibial epiphysis, and interobserver reliability was kappa = 0.836 for the distal femoral epiphysis and kappa = 0.885 for the proximal tibial epiphysis.)
