What this Trial Is About
This observational study focuses on children aged 3 to 18 years who have been diagnosed with brain tumors. It aims to assess how well magnetoencephalography (MEG), a brain imaging technique, works in preoperative evaluation compared to computed tomography (CT) and magnetic resonance imaging (MRI). The study seeks to understand how consistently MEG and CT/MRI locate tumors and how effective MEG is in guiding the extent of tumor removal before surgery. Participants will undergo both MEG and CT/MRI examinations before surgery to help determine tumor location and surgical planning. After surgery, they will be followed up at 1, 3, and 6 months with repeated MEG and CT/MRI scans. Neurological assessments and quality-of-life evaluations will also be conducted during these follow-up visits to monitor recovery and outcome. Throughout the study, researchers will track how closely MEG matches CT/MRI findings in tumor localization using a statistical measure called the Kappa coefficient. Participants will be monitored from enrollment until 12 months after surgery. The study involves regular imaging and clinical assessments but does not include any treatment interventions beyond standard care. Participation is expected to last approximately one year from enrollment through follow-up.
