Forensic age estimation is one of the concerns in living individuals especially in pubertal and post-pubertal age group. An evaluation of iliac crest using conventional projection radiography or digital radiography is common practice. However, recently few researchers have used sonography and magnetic resonance imaging for forensic age estimation with comparative results. The aim of present pilot study is to evaluate use of multidetecter CT images for iliac crest ossification.In the present study the Risser sign grading system was used. Total 56 tomograms were included consisting of 35 male and 21 female. The age group was from 11 years to 23 years. Considering the present study, fusions of iliac crest with ilium occurs earlier in females than males and are in agreement with other studies. Present study finds multidetecter CT very much helpful for assessing the ossification process.
