Carotid Artery Disease Assessed by Color Doppler Flow Imaging
With the sonographic technique of color Doppler flow imaging (CDFI), the spatial and temporal distribution of the color-coded Doppler signal can be visualized in realtime and superimposed on a high-resolution gray-scale image of tissue and

Computed Tomography of Temporal Bone Pneumatization
www.ajnr.orgComputed Tomography of Temporal Bone Pneumatization: 1. Normal Pattern and Morphology 551 The pneumatization of 141 "normal" temporal bones on computed tomography (CT) was evaluated in 100 patients (age range, 6-85 years), Because of the controversy surrounding the sclerotic squamomastoid (mastoid), temporal bones with this finding
Significance of CT and MR Findings in Sphenoid Sinus Disease
www.ajnr.orgIt is well recognized that disorders of the paranasal sinuses, and in particular of the sphenoid sinus, can cause significant neuroophthalmic morbidity [1 -4]. Re cently, we studied two patients at the University of Iowa Neuroophthalmology Clinic who presented with visual system disorders caused by sphenoid sinus disease.
