Imaging of the Cerebe llopontine Angle
Pathologic processes within the cerebellopontine angle (CPA) may present because of mass effect on local structures or on the pons or cerebellum. MR imaging is superior to CT for evaluation…
Imaging of the Central Skull Base
The central skull base (CSB) constitutes a frontier between the extracranial head and neck and the middle cranial fossa. The anatomy of this region is complex, containing most of the…
Imaging of Inflammatory and Infectious Diseases in the Temporal Bone
Inflammatory and infectious diseases of the temporal bone are a major indication to perform high-resolution CT and MR imaging studies. Such studies allow one to evaluate the extent of the…
Imaging of Temporal Bone Tumors
Tumoral lesions of the temporal bone are relatively rare. Cross-sectional imaging plays an important role in the description of extension of these lesions. In certain lesions, imaging characteristics are rather…
Molecular Imaging (PET) of Brain Tumors
Despite the recognized limitations of 18 Fluorodeoxyglucose positron emission tomography (FDG-PET) in brain tumor imaging due to the high background of normal gray matter, this imaging modality provides critical information…
Magnetic Resonance Perfusion and Permeability Imaging in Brain Tumors
Recent evidence suggests that vascular permeability and the presence of vascular endothelial growth factor/vascular permeability factor (VEGF/VPF) are important mediators of brain tumor growth in addition to angiogenesis. Perfusion and…
Imaging of the Central Skull Base
The central skull base (CSB) constitutes a frontier between the extracranial head and neck and the middle cranial fossa. The anatomy of this region is complex, containing most of the…
Brain Irradiation: Effects on Normal Brain Parenchyma and Radiation Injury
Radiation therapy is a major treatment modality for malignant and benign brain tumors. Concerns of radiation effects on the brain tissue and neurocognitive function and quality of life increase as…
Diffusion Imaging for Therapy Response Assessment of Brain Tumor
Advanced imaging provides insight into biophysical, physiologic, metabolic, or functional properties of tissues. Because water mobility is sensitive to cellular homeostasis, cellular density, and microstructural organization, it is considered a…
Therapeutic Advances in Malignant Glioma: Current Status and Future Prospects
This article reviews the current status and trends in the treatment of primary gliomas, focusing predominantly on glioblastoma. It also discusses the current standard of care and new targeted agents…
