摘要:

A technique for scintigraphically quantitating solid‐phase gastric emptying in the dog was developed in a Beagle model. The test meal was determined to empty in a linear fashion, indicating a solid‐phase label. The evaluation was performed on a group of dogs presented for gastrointestinal signs that were judged to have normal liquid barium sulfate fluoroscopic and radiographic studies. The results of this study indicate that this technique is valuable for identifying those patients with surgically correctable pyloric obstruction that exhibit normal gastric emptying of liquid bar

摘要:

The absence or presence of metastases on thoracic radiographs in 55 female dogs with mammary gland tumors was assessed by comparing the results of a single radiographic examination, using dorsoventral and left lateral views, with clinical and histologic follow‐up data. Radiographic abnormalities found in dogs with thoracic metastases were classified as well‐defined pulmonary nodules, ill‐defined pulmonary nodules, and involvement of pleural effusion. No obvious difference in the effect on the right or left lung lobes was found. The sensitivity, specificity and accuracy for the detection of thoracic metastases were 65%, 97%, and 87%, respect

摘要:

Heart volume mensuration was evaluated on conventional radiographs from eight normal cats in different body positions using computed tomography (CT). Heart volumes were calculated from orthogonal thoracic radiographs in ventral and dorsal recumbency and from radiographs exposed with a vertical X‐ray beam in dorsal and lateral recumbency using the formula for an ellipsoid body. Heart volumes were also estimated with CT in ventral, dorsal, right lateral and left lateral recumbency. No differences between heart volumes from CT in ventral recumbency and those from CT in right and left lateral recumbency were seen. In dorsal recumbency, however, significantly lower heart volumes were obtained. Heart volumes from CT in ventral recumbency were similar to those from radiographs in ventral and dorsal recumbency and dorsal/left lateral recumbency. Close correlation was also demonstrated between heart volumes from radiographs in dorsal/ left lateral recumbency and body weights of the eight cat

摘要:

Double‐constrast and positive‐contrast cystograms were performed in 12 dogs. After cystography, E. coli cystitis was induced in nine of the 12 dogs. The remaining three dogs were used as controls. Double contrast and positive‐contrast cystograms were repeated threee, seven and 14 days later. During cystography, bladders were distended to mild, moderate, and complete degrees of distention. Mucosal irregularity decreased with increasing bladder distention and was more likely to be seen on double‐contrast than on the positive‐contrast cystogram. When seen on both types of studies, mucosal irregularity was more obvious on double‐contrast than it was on the positive‐contrast custogram. Bladder wall thickness decreased with increasing distention; in some dogs with mild cystitis, abnormal wall thickness was masked by complete bladder distention. Bladder wall thickness could be measured more often on double‐contrast than on the positive contrast cystograms. Wall thickness measurments made on both types of studies were similar. It was concluded that lesions of mild to moderate cystitis may be missed when the bladder is completely distended, and that the double‐contrast cystogram is more sensetive for evaluating mucosal margivation and bladder wall thickness than is the positive

摘要:

Localization of99mTc‐MDP in lymph nodes was apparent on the three‐hour bone‐scan image in seven dogs. In six dogs injection or leakage of the radiopharmaceutical into the perivascular tissues was associated with subsequent uptake in an ipsilateral lymph node. In the remaining dog,99mTc‐MDP localized in a lymph node infiltrated by metastatic osteosarcoma. This aided staging of the tumor. Possible mechanisms of99mTc‐MDP localization in soft tissues are briefly

摘要:

The normal sonographic appearance of stomach, small bowel, and colon was determined in normal dogs of small, medium, and large breeds. In all dogs studied, the stomach wall ranged from 3 mm to 5 mm in thickness, and the small and large bowel wall ranged from 2 mm to 3 mm in thickness. Peristalsis was routinely observed in the stomach and small bowel, but not in the colon. Ultrasonic identification of five gastrointestinal wall layers corresponding to the mucosal surface, mucosa, submucosa, muscularis propria, and subserosa/serosa was possible. Specific segments of the gastrointestinal (GI) tract were isolated and scanned in a water bath. In one dog, ultrasonic and histologic findings were compared and confirmed the anatomical identification found with ultrasound. Similarities and differences between the ultrasonic appearance of the GI tract of humans and small animals are discussed.

摘要:

Transverse sections of the thorax of the Beagle were prepared, photographed, and compared with computerized tomographic scans and dissection specimens. Anatomical features were identified by these means with the aid of anatomical texts. A series of labeled photographs was produced to aid in the interpretation of computerized tomography and nuclear magnetic resonance scans.
