Normal canine pediatric gastrointestinal ultrasonography.

The normal sonographic appearance of the adult canine gastrointestinal tract has been described. Interpretation of abdominal ultrasonographic findings in puppies is difficult due to the lack of information on normal ultrasonographic findings. The gastrointestinal tract, jejunal lymph node size and the presence and appearance of abdominal fluid were investigated in 23 normal, 7-12-week-old Beagle puppies.

Ultrasonographic appearance of canine parvoviral enteritis in puppies.

The ultrasonographic appearance of the gastrointestinal tract of puppies suffering from parvoviral enteritis was characterized. Forty puppies between 6 and 24 weeks of age with confirmed canine parvoviral enteritis were examined ultrasonographically within 24 h of admission. Sonographic findings included fluid-filled small intestines in 92.

Association of preoperative magnetic resonance imaging findings with surgical features in Dachshunds with thoracolumbar intervertebral disk extrusion.

Objective: To evaluate the accuracy of specific magnetic resonance imaging (MRI) sequences in determining the site, lateralization, and extent of extruded intervertebral disk material (EIDM), compared with surgical findings, in Dachshunds with thoracolumbar intervertebral disk extrusion (TLIDE).

Design: Prospective clinical study.

Sample Population: 16 Dachshunds with clinical signs of intervertebral disk disease.

Ultrasonography of the liver, spleen, and urinary tract of the cheetah (Acinonyx jubatus).

Diseases of the abdomen of the cheetah (Acinonyx jubatus) include those affecting the liver, spleen, and urinary tract. The most common diseases of captive-bred cheetah are gastritis, gastric ulceration, glomerulosclerosis, and hepatic veno-occlusive disease, and are the most frequent causes of mortality in these animals. The purpose of this study was to describe the ultrasonographic anatomy of the normal liver, spleen, kidney, and urinary bladder of the anesthetized captive-bred cheetah.

Radiologic abnormalities of the appendicular skeleton of the lion (Panthera leo): incidental findings and Mycobacterium bovis-induced changes.

Thoracic and pelvic limbs from 15 euthanized free-ranging lions (Panthera leo), ranging in age from 16 to 144 months, underwent standard radiographic evaluation. All lions had tested positive for Mycobacterium bovis by means of a modified intradermal tuberculn test. The radiographs of six lions were normal and nine had incidental findings of which six had more than one lesion.

Transcutaneous ultrasonography of the abdomen in the normal common marmoset (Callithrix jacchus).

Ultrasonographic examinations were performed on 17 clinically healthy adult common marmosets to gain information about the normal abdominal echoanatomy. The marmosets were 1.5-9 years of age and weighed between 328 and 506g.

Radiographic anatomy of the thorax and abdomen of the common marmoset (Callithrix jacchus).

A standard radiographic procedure was developed for the thorax and abdomen in the common marmoset. A description and reference values for the corresponding radiographic anatomy are given. Radiographs were obtained from 17 anaesthetized healthy mature marmosets ranging from 1.

Radiographic gastrointestinal contrast study in the ostrich (Struthio camelus).

Ten gastrointestinal contrast studies were performed with barium on seven clinically healthy ostriches. Concentrations of 25-100% w/vol liquid barium sulfate at 7 and 10 ml/kg were administered by stomach tube after withholding food for 16 h. A 6-frame technique for left-to-right lateral views in standing and a 3-frame technique for the dorsoventral views in sternally recumbent adult ostriches were used for survey and contrast radiographs.
