Keynote webinar | Spotlight on sleep in brain health

LIVE: Thursday 2nd May 2024, 18:00-19:30 (CEST)

Quality sleep is essential for health. But what happens to our brains when sleep patterns are disturbed? Join our experts to explore the interplay between sleep disruption and neurological diseases, and the questions that you need to be asking your patients to help you prevent the harmful effects of sleep deprivation.

Abstract

Background

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.

Objective

To examine development of pelvic ossification centers by CT and determine normal appearance throughout childhood.

Materials and methods

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.

Results

Rate and progression of ossification and age at complete fusion vary with gender at the different ossification centers in the growing pelvis.

Conclusion

Knowledge of the normal CT appearance of ossification centers throughout childhood is important to differentiate the normal appearance from pathology.
