Magnetic resonance imaging of the posterior cranial fossa
1Berwyn Magnetic Resonance Center, IL 60402.
Abstract:
Magnetic resonance imaging has acquired a leading role in the assessment of the posterior cranial fossa, base of the skull, and neck. Several technical improvements, such as further refinement of surface coils, fast scanning, and paramagnetic agents, have enhanced the diagnostic capability of this imaging technique. It is extremely useful in the differentiation of pathologic processes arising from or involving the petrous pyramids, such as congenital cholesteatomas, cholesterol granulomas, and glomus tumors. It is the study of choice for both extra- and intra-axial lesions in the posterior cranial fossa. The magnetic characteristics of the most common lesions are reviewed in this paper.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
