ReviewCurrent role of functional MRI in the diagnosis of movement disorders.
The functional magnetic resonance (fMR) technique for brain mapping is a valuable tool for understanding both normal physiology and the dysfunction taking place in disorders of the brain. This article provides an overview of fMR imaging methods and their applications in the study of neurologic movement disorders. The article also reviews the current neuroimaging literature regarding parkinsonisms, dystonia, essential tremor, and Huntington disease, and includes a discussion of current methodological limitations and future directions for this exciting field.

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 bony foramina and canals of the skull base traversed by several neurovascular structures that can act as routes of spread for pathologic processes. ⋯ Crosssectional imaging is indispensable in the diagnosis, treatment planning, and follow-up of patients with CSB lesions. This review focuses on a systematic approach to this region based on an anatomic division that takes into account the major tissue constituents of the CSB.

This article reviews the embryology, anatomy, congenital anomaly, acquired disorders, degenerative diseases, neoplasms, and inflammatory and infectious disorders in the craniovertebral junction. The imaging characteristics and differential diagnoses of these lesions are provided. This review also focuses on the complimentary roles of different imaging modalities.

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 neoplastic and non-neoplastic pathologies involving this region.
