Spinal Parlance This chapter begins with a brief review of the anatomy of the spine. Imaging techniques are then discussed, followed by the normal imaging appearance of the spine on magnetic resonance (MR) imaging and computed tomography (CT). We then…
As opposed to the mucosal diseases of the head and neck, in which the differential diagnosis usually revolves around squamous cell carcinoma 90% of the time, the extramucosal space allows the radiologist to exercise finely honed skills in forming a…
The approach to this chapter on mucosal disease is divided along disease categories combining all regions except for the discussion of malignant masses. Because the basis for discussing cancers with clinicians is rooted in the TNM staging of the American…
To appreciate the pathogenesis of sinusitis, you must understand the normal anatomic pathways of mucociliary clearance in the paranasal sinuses ( Fig. 12-1 ). The cilia within the maxillary sinus propel the mucous stream in a starlike pattern from the…
The detailed bony anatomy of the vestibulocochlear structures of the temporal bone makes computed tomography (CT) the primary method of evaluating the erosive and inflammatory lesions of the temporal bone. Magnetic resonance imaging (MRI) also has an important role in…
Anatomy True story: in order to understand imaging of the skull base you are going to have to appreciate the normal anatomy first. We define the skull base as the region from the upper surface of the ethmoid bone and…
Time to play with the eye-ball—at first base, anatomy. The orbit is a cone-shaped structure made up of seven bones ( Fig. 9-1 ). The roof is formed by the orbital plate of the frontal bone anteriorly and the lesser…
Timing of Formation of Congenital Lesions If you think your ex utero life is complicated, wait till you see what goes on in utero! Understanding development of the central nervous system (CNS) aids in understanding congenital brain and spine anomalies…
The debate over whether a patient has atrophy or hydrocephalus has consumed an enormous number of pages in the neuroradiologic literature and whole sessions of national meetings. Why the fuss? Well, the implications as far as prognosis and treatment are…
White matter diseases are heterogeneous conditions linked together because they involve the same substrate. Magnetic resonance imaging (MRI) is quite sensitive and, when combined with age and other pertinent clinical information, provides a reasonable amount of specificity for white matter…
