摘要:

The nephrographic phase of the excretory urogram may be used to qualitatively assess some functional aspects of renal disease. Functional abnormalities of the kidney which alter the normal pattern of nephrographic opacification may be associated with renal perfusion abnormalities, glomerular dysfunction, intra or extrarenal obstruction, renal tubular necrosis and adverse reactions (renal or systemic) to iodinated contrast media. The time of maximum nephrographic opacification following intravenous injection of contrast medium and variations in nephrographic opacity before and after maximum opacification may help differentiate these disease processes. Standard radiographic and urographic techniques must be used to prevent changes caused by variations in contrast medium dosage and filming sequence from being misinterpreted as functional renal abnormalities.

摘要:

A 13‐year‐old male Setter‐Springer crossbred dog was presented with signs of acute peritonitis three days after blunt abdominal trauma. In abdominal radiographs, a bubbly accumulation of gas in the central and cranioventral parts of the liver silhouette and mild peritoneal effusion were seen. At laparatomy, firm, necrotic, nodular hepatic masses containing gas were found to be ruptured. The histologic diagnoses were hepatic adenoma with hepatic necrosis and nodular hepatic hyperplasia. The pathogenesis of hepatic abscessation and the radiographic differential diagnosis of extraluminal abdominal gas are disc

摘要:

Difficulty in recognition of some diaphragmatic hernias in dogs have stimulated the authors to develop a diagnostic method consisting of selective angiography of the cranial mesenteric and celiac arteries. The basis for the experimen was that each herniated visceral organ is usually displaced with its vessels. The experiment was carried out on 14 mongrel dogs. Four dogs served as controls. Different kinds of diaphragmatic hernias were surgically created in 10 dogs. Survey abdominal radiographs, gastrointestinal tract contrast studies and selective abdominal angiography were performed 14 days later. In angiograms of dogs with omental diaphragmatic hernias, displacement of branches of the left gastroepiploic artery into the thorax was seen. In angiograms of dogs with hepatic diaphragmatic hernias, branches of the common hepatic artery were seen to enter the thorax. In dogs with herniated small intestine, the jejunal branches of the cranial mesenteric artery were seen entering the thorax. Potential possibilities of selective abdominal angiography for diagnosis of diaphragmatic hernias are discussed.

摘要:

Twelve dogs of various breeds, age and weight were injected with xylazine hydrochloride by intravenous and intramuscular routes at various doses. Radiographs of the abdomen were made prior to and at 30, 60 and 90 minutes after injection. The drug produced dilatation of the stomach and the intestines. Radiographic changes were consistent with gastric dilatation and paralytic ileus

摘要:

A 9‐year‐old neutered female mixed breed dog was examined for productive coughing, gagging, increased respiratory effort and restlessness. In survey chest radiographs a soft tissue opacity was present in the right middle lung lobe. In horizontal‐beam radiographs, it was apparent that the opacity was a thin‐walled cyst containing air and fluid. Peribronchial infiltration and bronchial dilation were present in all lung lobes. At necropsy, a diagnosis of chronic bronchitis and bronchiolitis and cylindrical and cystic bronchiectasis was made. Acquired bronchiectasis may result from any disease process which weakens the bronchial wall or obstructs drainage. Three forms of bronchiectasis have been described in man: cylindrical, saccular and cystic. Cylindrical bronchiectasis is tubular distention of larger, thick‐walled bronchi; saccular bronchiectasis is circumscribed outpocketing of intermediate‐sized bronchi and cystic bronchiectasis is a more pronounced manifestation of saccular bronchiectasis in terminal bronchi. Cylindrical and saccular bronchiectasis have been described in the dog; cystic bronchiectasis has not been described in the dog. Generalized bronchiectasis is an incurable condition due to the irreversible bronchial pathologic changes. Focal bronchiectasis can be surgically corrected by lobectomy and the prognosis is good. Aggressive antibiotic therapy should be used to treat chronic bronchitis in an effort to prevent bronchial destruction and development of bro
