摘要:

The purpose of the study was to provide a reference for xeroradiographic and conventional radio‐graphic anatomy of the orange‐winged Amazon parrot (Amazona amazonica amazonica) as a representative of medium‐sized psittacine birds that are commonly kept as pets. The head, body, wing, and pelvic limb of a mature bird were radiographed using xeroradiographic and conventional radiographic techniques. Ten xeroradiographs and ten corresponding radiographs were selected, and the xeroradiographs labeled to illustrate the normal radiographic anatomy of these regions. Also included is a short discussion of unique avian anatomic features which are important to clinical evalu

摘要:

The psittacine skull is a complex anatomic structure, frequently traumatized but difficult to adequately image with standard radiographic procedures. Multiple views including a ventrodorsal, a lateral, and complementary oblique projections are necessary to fully evaluate potential skull fractures in the avian patient. Magnification radiography is a relatively easy procedure that aids the review of small osseous structures. Familiarity with psittacine skull anatomy greatly facilitates radiographic interpretation of cranial trauma.

摘要:

Sonographic findings of 18 dogs and four cats with gastrointestinal (GI) diseases were reviewed. Wall thickness, wall layer identification, wall symmetry, extension of the lesion, nature of the GI contents, motility, and regional and/or systemic involvement were recorded for each animal. Ultrasonographic appearance of gastrointestinal neoplasms, gastrointestinal obstruction, ileus, intussusception, inflammatory GI diseases, and congenital disorders are discussed.

摘要:

Volumetrically correct, three‐dimensional color images of the sea otter, (Enhydra lutris), were generated from computed tomographic (CT) data using a Sun 3/160 workstation and a Pixar Imaging Computer. These images could be displayed as static images (1024×768) or rotated about any axis in real‐time by displaying sequential rotation sequences generated by the Pixar Imaging Computer. The images provided realistic depth of field through overshadowing and differential opacification. This was obtained through an opacification algorithm which traced rays from a selected viewing plane through colored gel volumes, and calculated absorbance percentages as a function of the transparency of the gels penetrated. Reconstructions of this type serve as alternative anatomy tutorials for species otherwise unavailable for routine dissection. They also permit topographical studies without interfering with populations of endangered ani

摘要:

Survey radiography, linear tomography, and computed tomography were used to image cribriform plate lesions that were created experimentally using intramedullary pins in 18 dog cadaver skulls. Computed and linear tomographic images were taken along the dorsal imaging plane. Studies were independently reviewed by five observers. Results were combined so that the relative sensitivity, specificity, and accuracy of each imaging technique could be compared using chi‐square analysis. Computed tomography proved to be significantly more sensitive and accurate (p<0.05) than either linear tomography or survey radiography. Computed tomographic images were consistently of good to excellent quality for imaging the cribriform plate. It was concluded that computed tomography of the skull using a dorsal imaging plane was the best available imaging modality for detecting 3‐mm and 5‐mm experimentally created cribriform plate de

摘要:

Zinc poisoning was identified in a 4‐year‐old dog secondary to ingestion and gastric retention of two pennies. The pennies were identified radiographically and were observed to dissolve almost completely over a 2‐day period. The dog died 2 days after laparotomy and gastrotomy. Renal tubular necrosis and hepatic degeneration were identified histologically. Radiologists should be aware of the potential for intoxication from pennies and zinc nuts when these foreign objects are retained in the st

Tracheal collapse was diagnosed radiographically in an eight‐day‐old Yorkshire‐cross piglet presented with acute onset of inspiratory dyspnea. The diagnosis was confirmed by gross and microscopic pathology. This is the first reported example of tracheal collapse in

摘要:

Radiographs were made of the skull of a 1.5‐year‐old and a 3‐year‐old camel for the purpose of assessing and describing the radiographic anatomy. Radiographic anatomy was compared with results from gross dissection of 5 additional camel specimens. Camel skull anatomy was related to that of the horse and ox. Obvious differences were found. These include in the camel, large occipital condules, a notched foramen magnum, an intracranial projection for the interparietal bone, and small paranasal sinuses. Other minor differences are detailed in t

摘要:

An associated ocular and skeletal dysplasia in Labrador Retrievers is caused by one abnormal gene which has recessive effects on the skeleton and incompletely dominant effects on the eye. The forelimbs of normal and affected pups were radiographed between birth and 156 days of age and the length of the radius and ulna measured. There was a significant difference in the mean length of these bones in normal and affected pups at birth and this difference was maintained over the period of observation. Similar differences were observed in purebred Labrador Retrievers and in Labrador Retriever‐Beagle crosses. The results of this study suggest that the length of the radius and ulna could be used to identify pups affected by this syndrome if test matings with affected animals were done to identify carrier animals. Abnormal shape of the radius and ulna, which is seen in animals affected with this syndrome, should be used to augment the accuracy of identification of puppies affected by this syndrom
