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.

A large number of entities can present as a suprasellar or parasellar mass. These include benign and malignant tumors as well as inflammatory and other lesions that can mimic a neoplasm. Imaging features and distinguishing characteristics of juxtasellar masses are described.

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.

ReviewProton MR spectroscopy in inflammatory and infectious brain disorders.
This article reviews the proton MR spectroscopy literature regarding brain infarction and inflammatory diseases. We examine the salient findings reported for bacterial abscesses, intracranial tuberculomas, Creutzfeldt-Jakob disease, herpes simplex encephalitis and HIV. These processes demonstrate specific metabolic profiles which may be useful in differential diagnosis. The results reported in the literature support the view that MR spectroscopy can be employed in longitudinal studies to monitor the response to therapy and therefore may lead to individual optimized treatment effectiveness.
