Four unusual pelvic masses, studied by CT and gray scale ultrasonography, demonstrate the comparative values of these modalities for this area of the body. In each instance a significant contribution to the diagnosis was made by one or both techniques. The ultrasound study provides a somewhat better differentiation of solid from cystic lesions, but the CT… (More)
Orbital blow-out fractures were experimentally created in eight human cadavers. Each orbit underwent conventional radiographic studies, complex motion tomography, and computed tomographic examinations. A comparison of the three modalities was made. Anatomical correlation was obtained by dissecting the orbits. The significance of medial-wall fractures and… (More)
The diagnosis of empty sella was made correctly by CT scanning in 100% of 19 cases studied.
The presence of a bifid posterior arch of the atlas has been regarded as a contraindication to the wiring of C1-2 for atlantoaxial arthrodesis. Three cases with C1 posterior spondyloschisis are presented with successful atlantoaxial arthrodesis using laterally placed wires to avoid the midline defect of the atlas. An experimental study of the efficacy of… (More)
Thirty cases of orbital floor blow-out fractures proven by tomography were retrospectively reviewed to determine the accuracy of the plain films. Using the maximum diameter from the tomograms, the area and volume of the fractures were calculated and correlated with the presence of diplopia and enophthalmos at the time of presentation and at subsequent… (More)
By applying a wide window to computed tomography (CT) images, excellent detail of the skull base has been obtained. This technique has been apllied to lesions involving the sellar, parasellar, sphenoid wing, petrous bone, clival, and foramen magnum regions. Thus, CT has proved to have an additional dimension in the delineation of pathology.
A method for obtaining coronal scans of the cranium is described in which a scanner with a tilting gantry is used. Computed coronal tomography is especially useful in the high convexity area and in the suprasellar and foramen magnum regions.
