The pelvis is composed of three paired primary ossification centers: the pubis, the ischium and the ilium. During maturation, multiple secondary ossification centers can be seen in the synchondroses between these bones and in the pelvic apophyses. The fragmented appearance of these centers can be confused with pathology.
To examine development of pelvic ossification centers by CT and determine normal appearance throughout childhood.
Three pediatric radiologists reviewed 325 pelvic CT scans in children and young adults 5-18 years old and graded 6 pelvic ossification centers to evaluate maturational changes in critical structures.
Rate and progression of ossification and age at complete fusion vary with gender at the different ossification centers in the growing pelvis.
Knowledge of the normal CT appearance of ossification centers throughout childhood is important to differentiate the normal appearance from pathology.
骨盆由三个成对的主要骨化中心组成：耻骨、坐骨和髂骨。在成熟过程中，在这些骨头之间的软骨结合处以及骨盆的骨突中可以看到多个次级骨化中心。这些中心的碎片状外观可能会与病变相混淆。
通过CT检查骨盆骨化中心的发育情况，并确定整个儿童期的正常表现。
三位儿科放射科医生回顾了325例5至18岁儿童及青年成人的骨盆CT扫描，并对6个骨盆骨化中心进行分级，以评估关键结构的成熟变化。
在生长中的骨盆中，不同骨化中心的骨化速率、进展情况以及完全融合的年龄因性别而异。
了解整个儿童期骨化中心的正常CT表现对于区分正常表现与病变很重要。
