Estimating the age of the ossification of the iliac crest may help determine the legal age. For this purpose, both anthropological and radiological methods (conventional radiography, ultrasound, Tomography, and MRI) have been used to study different systems.
The present study aimed to to evaluate the iliac crest apophysis for age estimation through multidetector computed tomography (MDCT) in 10- to 29-year-old individuals.
This retrospective study was carried out on 10- to 29-year-old individuals who underwent pelvic CT examinations for different reasons in Imam Khomeini and Golestan hospitals of Ahwaz during 2016-2018. The CT examinations of the iliac crest apophysis of 531 patients (267 females and 264 males) were evaluated based on the Kreitner's four-stage system.
According to the Kreitner's four-stage system, the minimum age for both sides of the pelvis at stage 2 for girls and boys was 12 years and 13 years, respectively. However, at stage 3, the minimum age for girls and boys was 15 and 17 years, respectively. Accordingly, stage 4 was first observed in boys at age 17 on both sides of the pelvis. In contrast, it appeared in girls at the age of 20 on the right side.
Along with the findings of other studies, the results showed that multidetector computed tomography (MDCT) is recommended for iliac crest in retrospective cases (where pelvic CT scans already exist), and it may be considered as a supportive method for age-estimation purposes. Moreover, when CT images are used along with other age estimation methods, they provide physicians with valuable supplementary information.
估计髂嵴骨化年龄有助于确定法定年龄。为此，人类学和放射学方法（传统放射摄影、超声、体层摄影和磁共振成像）均已用于研究不同系统。
本研究旨在通过多排螺旋计算机断层扫描（MDCT）对10至29岁个体的髂嵴骨骺进行年龄评估。
这项回顾性研究针对2016年至2018年期间在阿瓦士的伊玛目霍梅尼医院和戈勒斯坦医院因不同原因接受盆腔CT检查的10至29岁个体展开。根据Kreitner的四阶段系统对531例患者（267名女性和264名男性）的髂嵴骨骺CT检查进行评估。
根据Kreitner的四阶段系统，女孩和男孩骨盆两侧在第2阶段的最小年龄分别为12岁和13岁。然而，在第3阶段，女孩和男孩的最小年龄分别为15岁和17岁。因此，第4阶段首先在17岁男孩的骨盆两侧观察到。相比之下，右侧在20岁女孩中出现。
与其他研究结果一致，结果表明，对于回顾性病例（已有盆腔CT扫描），多排螺旋计算机断层扫描（MDCT）适用于髂嵴，可被视为一种用于年龄估计目的的辅助方法。此外，当CT图像与其他年龄估计方法一起使用时，可为医生提供有价值的补充信息。
