Abstract.

Although craniosynostosis can be easily diagnosed with a complete evaluation including a detailed pregnancy, birth, and sleeping position history, as well as a thorough physical examination, imaging is often needed to confirm the diagnosis and to create the appropriate treatment plan. CT is the preferred imaging technique for accurate and complete assessment. The aim of this study is to present the radiologic features of 3D-CT in patients with craniosynostosis, with emphasis given to diagnostic criteria, surgical repair and postoperative follow-up imaging. A total of 63 patients records were reviewed. The inclusion criteria were patients clinically diagnosed with nonsyndromic craniosynostosis, less than 3 years of age, who underwent CT imaging examination in order to formulate the appropriatetreatment plan, which included primary surgery with open cranial vault reconstruction. The high diagnostic performance of CT with 3D surfacerendered reconstructions was pointed out. Specific imaging goals including detailed characterization of the number of fused sutures, extent of suture involvement, complexity of 3D calvarial deformity, underlying brain anomaly, correct treatment plan establishment and detection of postoperative complications were achieved. 3D-CT appears as the imaging modality with the best diagnostic performance. However, it is important to define clearly the questions to be addressed by any imaging study, in order to minimize the unnecessary exposure of infants to radiation.
