<unk>  as visualized on an MRI<unk>  is diagnosed through a combination of diagnostic processes: * Initially, a doctor will interview the patient and do a clinical exam, which will include a neurological examination. * A CT scan of the brain, and/or an MRI scan of the brain and spine, will be performed. A special dye may be injected into a vein before these scans to provide contrast and make tumors easier to see. * For children experiencing seizures, an EEG might be part of the diagnostic process (the goal being to record the brain's electrical activity in order to identify and localize seizure activity). * Finally, a biopsy of the tumor, taken through a needle during a simple surgical procedure, helps to confirm the diagnosis.
