Imaging of Jugular Foramen
Jugular foramen, albeit complex, is essentially a bony conduit transmitting nerves and vessels from the posterior cranial fossa to the nasopharyngeal carotid space. In addition to its intrinsic pathologic conditions,…
Petrous Apex
The petrous apex is the most medial portion of the temporal bone that cannot be directly examined on clinical examination. The referring physician completely relies on imaging and radiologic interpretation….
Intraoperative Mapping for Tumor Resection
This article describes the rationale, indications, and modality for intraoperative brain mapping for safe and effective surgical removal of tumors located within functional brain areas. Intraoperative mapping refers to a…
Imaging of the Anterior Skull Base
This article briefly discusses the imaging approach to lesions of the anterior skull base. A brief review of normal anatomy and imaging techniques is followed by a discussion about common…
Imaging of the Facial Nerve
A variety of congenital, traumatic, vascular, inflammatory, and neoplastic processes may affect the facial nerve. Prudent use of CT and MR imaging combined with a complete understanding of facial nerve…
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…
