摘要:

The purpose of this study was to produce a comprehensive anatomic atlas of CT anatomy of the dog for use by veterinary radiologists, clinicians, and surgeons. Whole‐body CT images of two mature beagle dogs were made with the dogs supported in sternal recumbency and using a slice thickness of 13 mm. At the end of the CT session, each dog was euthanized, and while carefully maintaining the same position, the body was frozen. The body was then sectioned at 13‐mm intervals, with the cuts matched as closely as possible to the CT slices. The frozen sections were cleaned, photographed, and radiographed using xeroradiography. Each CT image was studied and compared with its corresponding xeroradiograph and anatomic section to assist in the accurate identification of specific structures. Clinically relevant anatomic structures were identified and labeled in the three corresponding photographs (CT image, xeroradiograph, and anatomic section). In previous papers, the head and neck, and the thorax and cranial abdomen of the mesaticephalic (beagle) dog were presented. In this paper, the caudal part of the abdomen and pelvis of the bitch and male dog are presen

摘要:

Iohexol was administered orally in five dogs. The dose, gastrointestinal (GI) transit time, appearance of mucosal patterns and side effects were studied. Three different doses (525, 700, 875 mgI/kg) were used in each dog at 1‐week intervals. GI transit time was rapid. In each dose, gastric emptying commenced immediately after administration of the contrast medium, and was completed within 30–60 min with doses of 525–700 mgI/kg and 90–120 min with 875 mgI/kg. Large intestinal filling was observed within 60‐90 min. In the majority of studies, the mucosal border appeared as a thin homogeneous halo of lucency surrounding the more opaque bowel lumen contents. The contrast intensity was not adequate with the lowest dose. The image quality did not deteriorate along the GI tract. No adverse reactions were found. Iohexol is an alternative GI contrast medium in the dog when contrast media are contra

摘要:

A 7‐year‐old, intact, anestrous, female Doberman pinscher was presented with anorexia and hindlimb swelling of three days duration. Renal failure was documented. Survey radiographs revealed patchy alveolar consolidation and bilateral renomegaly with increased retroperitoneal and sublumbar soft tissue opacification. Renal ultrasonography showed bilateral hydronephrosis with ectatic ureters. A retroperitoneal carcinoma was identified via fine needle aspiration. Percutaneous nephropyelocentesis and antegrade nephrography further delineated the hydronephrosis and ureteral obstruct

摘要:

A 2‐year‐old Arabian filly was presented for evaluation after falling backwards. The injury was manifest radiographically by the presence of air within the subarachnoid space of the calvarium and the cervical spinal canal. Radiographic findings resulted from communication of the sphenopalatine sinus with the subarachnoid space as a sequela to a fracture involving the presphenoid b

摘要:

Survey radiographic studies of the lumbosacral region for 93 normal dogs and for 26 dogs with confirmed degenerative lumbosacral stenosis were reviewed. Normal dogs were divided into 9 groups based on age and body weight. For normal dogs, increasing age and body weight were associated with a decreased ability to extend the lumbosacral joint and with increased incidence and severity of spondylosis. Transitional lumbosacral vertebrae and evidence of lumbosacral disc space collapse were very infrequent findings, and the pivot point for lumbosacral motion was consistently centered over the lumbosacral disc space. Relative to an age/weight matched sub‐population of normal dogs, dogs with degenerative lumbosacral stenosis had similar mean normalized lumbosacral vertebral canal height, larger mean neutral lumbosacral angle, decreased extension of the lumbosacral joint, increased flexion of the lumbosacral joint, reduced lumbosacral range of motion, increased lumbosacral dynamic malalignment, higher incidence and severity of spondylosis, higher incidence of transitional vertebrae, and higher incidence of lumbosacral disc space collapse. A logistic model based strictly on radiographic parameters was able to discriminate normal from affected dogs with an overall accuracy rate of 86

摘要:

A deep muscle abscess was diagnosed in a horse with a clinical history of a painful swelling in the left gluteal region. The thick walled hypoechoic structure seen on presentation and the multiloculated hyperechoic mass seen on reevaluation are common Ultrasonographic appearances of abscesses. Ultrasonographic evaluation allowed characterization of a chronic mass with subsequent successful surgery and treatment.
