Skull sutures normally found in pediatric patients can make it difficult to differentiate a fracture from normal suture lines.⁷,⁹ CT with sagittal and coronal reformatted series as well as 3-dimensional shaded-surface volume-rendered images can accurately differentiate between fractures and sutures.⁹ Fractures have sharp borders and increase in diameter as they approach sutures.
