The combination of surgery and radiation remains the most effective treatment for tumors affecting the central nervous system. This article reviews surgical therapy for brain tumors. Special attention is paid to new approaches to brain tumor therapy and to the interaction between neuroimaging and successful surgery.

Review Comparative StudySedation for pediatric imaging studies.
This article discusses safe sedation for pediatric imaging. Emphasis is placed upon implementation of an institutional sedation program according to guidelines of the American Academy of Pediatrics. Standards for patient assessment and preparation, sedative administration, monitoring, and discharge are reviewed. A comparison of available sedative agents is also provided.

ReviewImaging of the pediatric orbit and visual pathways: computed tomography and magnetic resonance imaging.
Techniques for pediatric MR imaging and computed tomography and anatomy of the orbit and intracranial visual pathways are presented and reviewed in this article. Imaging findings are presented for the following categories of abnormality: a) orbital anomalies related to congenital disorders of the brain, b) disorders of the orbit (ocular, nonocular, or multicompartmental), c) disorders of the intracranial visual pathways (suprasellar cistern, optic radiations, or occipital cortex), and d) disorders of gaze (extraocular muscles, cranial nerves, and brainstem). Careful assessment of the clinical findings, anatomic location of the visual impairment, and familiarity with disorders that often affect pediatric patients are helpful in guiding neuroimaging evaluation of the child with ocular, orbital, or central patterns of visual disturbance.

Primary central nervous system tumors are the most common solid tumors in children. Their overall frequency is second only to that of leukemia. Many brain tumors in children are relatively benign and can be successfully treated with surgery or radiation therapy, but progress in treating the malignant forms of these neoplasms lags behind that for leukemias and other solid tumors. This article discusses how MR spectroscopy is used to manage the individualized treatment of children with brain tumors.
