In the past decade, numerous advances in the understanding of brain tumor physiology, tumor imaging, and tumor therapy have been attained. In some cases, these advances have resulted from refinements…
The use of biomarkers of microvascular structure and function from perfusion and permeability imaging is now well established in neuro-oncological research. There remain significant challenges to be overcome before these…
The advanced imaging techniques outlined in this article are only slowly establishing their place in surgical practice. Even a low risk of false information is unacceptable in neurosurgery, thus decision-making…
Diffuse gliomas in adults continue to have a dismal prognosis with the current standard therapeutic methods, including maximal surgical resection, radiation, and chemotherapy. The pathogenesis of adult glioma is complex,…
To keep up with advances in central nervous system (CNS) tumor diagnosis and discovery of new entities, the classification of these tumors requires periodic review and revision. Since the initial…
This article summarizes current state-of-the-art techniques used in the management of pediatric neurologic emergencies. Solutions to challenges faced by the radiologist, including the selection of an appropriate modality for an…
This article outlines a practical imaging approach to CNS infection and reviews 5 basic imaging patterns commonly seen: (1) extra-axial lesion, (2) ring-enhancing lesion, (3) temporal lobe lesion, (4) basal…
For over 20 years, conventional MR imaging has been used for assessing brain tumors. However, conventional MR imaging tends to underestimate the extent of the tumor, perhaps leading to suboptimal…
Neck infections are fairly common in the emergency setting, affecting a broad spectrum of the patient population. Care should be taken not only to distinguish these conditions from other noninfectious…
Nontraumatic (or spontaneous) intracranial hemorrhage most commonly involves the brain parenchyma and subarachnoid space. This entity accounts for at least 10% of strokes and is a leading cause of death…
