Clinical TrialAccuracy of intraoperative registration during electromagnetic neuronavigation in intracranial procedures performed in children.
The aim of the study was to evaluate registration accuracy in an electromagnetic navigation system applied to image-guided intracranial procedures in children. ⋯ Electromagnetic neuronavigation, which does not require firm head fixation, can be used in the youngest age group. Nevertheless, registration accuracy is lower in newborns and infants. Neither imaging modality (MRI or CT) used for creation of a three-dimensional model of the patient's head nor registration of more than 6 landmarks have an impact on registration accuracy.
