摘要:

The purpose of the project was to provide a reference for radiographic anatomy of the developing equine foredigit and metacarpophalangeal region. Using xeroradiographic techniques, both foredigits and meta‐carpophalangeal regions of six Quarter Horse foals were radiographed at one day of age and at two‐week intervals until the foals were six weeks old. The foals were then radiographed at four‐week intervals until they were 12 months old. This report deals specifically with the first six months of postnatal development. Lateromedial and dorsopalmar xeroradiographs of each foredigit and metacarpophalangeal region and a dorsal 65° proximal‐palmarodistal oblique view of the distal part of the digit were made for each examination. The foals were weighed and measured at the withers immediately prior to each examination. Representative xeroradiographs were selected and appropriately labeled to demonstrate normal radio‐graphic anatomy of these regions. First radiographic appearance of distal epiphyseal ossification in metacarpal 2 and metacarpal 4 was extremely variable and ranged from four to 38 weeks. Radiographic closure of the proximal physis of the middle phalanx ranged from 18 to 30 weeks (mean = 26 weeks). Radiographic closure of the proximal physis of the proximal phalanx ranged from 22 to 38 weeks (mean = 30 weeks). Radiographic closure of the distal physis of metacarpal 3 ranged from 18 to 38 weeks (mean = 29 weeks). When xeroradiographic physeal closure times were compared with scintigraphic closure times from a companion study, results correlated very well. A crena marginis solearis was observed in ten of 12 forelimbs (83.3%); its first radiographic appearance ranged from four to 22 weeks (mean = 11–12 weeks). A consistent groove in the hoof wall, which formed near the time of birth and moved distally at about 3 mm per week, was noted. The groove's distance from the proximal hoof border may be useful in age estimation of foals less than 18

摘要:

Both foredigits and metacarpophalangeal joints of six Quarter Horse foals were scanned serially to six months of age using99Tc‐methylene diphosphonate. Dorsal scans were made on day 1 and at two, four, six, ten, 14, 18, 22 and 26 weeks of age. Scans were assessed visually for distal third metacarpal, proximal phalangeal, and middle phalangeal physeal appearance and closure. Scans were also evaluated by computer region‐of‐interest (ROI) and line‐profile analysis to characterize the physes quantitatively. Physeal region radioactivity relative to a disphyseal reference region was greatest at four weeks for all physes. Scintigraphic physeal closure of all physes occurred at approximately six months of age with a range of four and one half to greater than six months. The study was conducted to allow better assessment of diffuse and focal physeal disease by determining developmental times at which normal physeal region radioactivity has decreased enough to not obscure abnormal radioactivity and by quantifying scintigraphic physeal appearance which enables computer analysis to detect visually indeterminate physeal abnorm

摘要:

The detection of small amounts of free peritoneal fluid in the canine patient can be a diagnostic dilemma. Ultrasonography and radiography have been advocated to detect intraabdominal fluid not detectable by physical exam. The purpose of this study was to determine the more sensitive method for detecting small amounts of free peritoneal fluid. Ultrasound examinations and radiographs were performed after increments (1 ml/lb body weight) of fluid were injected intraperitoneally. Ultrasonography detected fluid in one animal at 2 ml/lb. AH other animals had fluid detected at 3 ml/lb. With radiographs fluid could be detected with a high degree of accuracy at 4 ml/lb. The lateral view was more accurate than the ventrodorsal view in detecting fluid. The authors concluded that Ultrasonography is more sensitive than radiography and is the method of choice to detect small amounts of free peritoneal fluid.

摘要:

Chronic proliferative synovitis is an insidious condition affecting the metacarpophalangeal joints of horses. It results in proliferation of the synovium in the dorsal pouch of the joint in question. Treatment involves surgical excision, thus confirmation of the lesion is important. Classically this has been achieved by means of positive‐contrast arthrography, but this article addresses the attributes of ultrasonography, a less invasive imaging techniqu

摘要:

Between 1978 and 1986, nine cats with nasal tumors were treated with radiation therapy. Rhinotomy was performed in six cats and diagnostic biopsy procedures were performed in three cats. For four of the specimens, a histologic review was significantly different from the initial diagnosis. At the time of analysis, one cat was alive and disease free 26.3 months after the first radiation therapy treatment; two of the cats were dead as a result of local recurrence, four were dead because of unrelated causes, and two were dead of unknown causes. The mean and median survival of cats in this study were 27.9 and 20.8 months, respectively, following the first radiation therapy. There was a 66.7% one‐year, 44% two‐year, and 33% three‐year survival rate. Complications of the surgery and radiation therapy were minimal. In conclusion, the histologic evaluation of nasal neoplasms in cats is not straightforward and may require specialized histologic technics for accurate diagnosis. Radiation appears to be safe and may be efficacious in local control of feline nasal t

摘要:

Diagnostic radiology of the esophagus, stomach, small and large intestine, mesentery, and pancreas is reviewed. Survey and contrast radiography remain the principal imaging methods used to evaluate gastrointestinal diseases in animals. Of the other imaging techniques, scintigraphy has potential in assessment of esophageal and gastric motility disorders, and detection of intestinal hemorrhage. Ultrasonography is useful for imaging the pancreas and gastrointestinal mass lesions.
