USE OF COMPUTED TOMOGRAPHY AND COMPUTED TOMOGRAPHIC MYELOGRAPHY FOR ASSESSMENT OF SPINAL TUMORAL CALCINOSIS IN A DOG     

Luc M. Van  Ham  DVM  Henri J. van  Bree  DVM  PhD  Mulenda  Tshamala  DVM  Hendrik  Thoonen  DVM 《Veterinary radiology & ultrasound》1995,36(2):115-118

Spinal tumoral calcinosis is reported in a Berner sennenhund puppy. The condition was manifested clinically as a non-ambulatory tetraparesis associated with neck pain. On survey radiographs there was a focal calcified mass at the atlantoaxial articulation. Computed tomography and computed tomographic myelography gave additional information on the extent of the mass and on the degree of spinal cord compression. The mass was removed surgically and the dog made a complete recovery.  相似文献   

USE OF TRANSCOLONIC ¹²³I-IODOAMPHETAMINE TO DIAGNOSE SPONTANEOUS PORTOSYSTEMIC SHUNTS IN 18 DOGS     

Philip D.  Koblik  DVM  MA  Chi-K  Yen  MD  William J.  Hornof  DVM  MS  Pamela  Whiting  DVM  Paul  Fisher  BS 《Veterinary radiology & ultrasound》1989,30(2):67-73

Transcolonic ¹²³I-Iodoamphetamine is rapidly absorbed across the colonic mucosa and binds to amine receptors in the liver and lungs. During the first ten minutes following colonic administration, a simple ratio of lung counts to lung counts plus liver counts provides an accurate estimate of the fraction of portal blood that bypasses hepatic sinusoids in dogs with portosystemic shunts. Studies were performed on 24 dogs with suspect portosystemic shunt. Shunt fraction values for 18 dogs with surgically confirmed portosystemic shunt were obviously higher than published values for normal dogs, and also significantly higher than values for the other six dogs, later confirmed to lack shunts. Postoperative studies were repeated on ten dogs with single shunt vessels 1–2 days after shunt closure. Total shunt ligation resulted in normal postoperative shunt fraction, whereas partial shunt ligation resulted in persistant elevation of shunt fraction. Transcolonic iodoamphetamine scintigraphy is noninvasive, easy to perform, and provides an accurate method to diagnose dogs with portosystemic shunt.  相似文献   

A SACRAL LESION RESEMBLING OSTEOCHONDROSIS IN THE GERMAN SHEPHERD DOG

More than 30% (21 of 65) of German Shepherd dogs with clinical signs of cauda equina compression had radiographic and pathologic abnormalities compatible with osteochondrosis of the sacral endplate. Most of these dogs had a defect in the dorsal part of the sacral endplate and a detached bone fragment in the vertebral canal. Similar lesions were also found in growing and young adult dogs without clinical signs. The dogs with clinical signs of cauda equina compression also had severe degenerative disc disease with protrusion of the lumbosacral disc and compression of the cauda equina, suggesting that the signs of cauda equina compression more likely were related to the secondary degenerative changes (disc protrusions) rather than the primary disease. Clinically normal German Shepherds with sacral osteochondrosis usually were younger than 18 months, the dogs with cauda equina compression and sacral osteochondrosis older than 18 months (mean age 4.8 years). On the average, these dogs were two years younger as compared to dogs with cauda equina compression without sacral osteochondrosis. Male dogs are more often affected than females (5:1). There is a breed predisposition: in dogs other than German Shepherds, osteochondrosis of the sacral endplate seems to be extremely rare.  相似文献   

ERG findings in three hypothyroid adult dogs with and without levothyroxine treatment     

Philippe Durieux  F. Rigaudière  J.-F. LeGargasson  S. G. Rosolen 《Veterinary ophthalmology》2008,11(6):406-411

Purpose To evaluate the effects of levothyroxine (LTh) on the electroretinogram (ERG) of adult dogs. Material and methods Binocular, full field photopic and scotopic ERGs were recorded from an anesthetized Maltese Bichon cross (MB), a Yorkshire Terrier (YT) and a Shetland Sheepdog (SS) affected with hypothyroidism and treated with a daily dose of LTh at 20 µg/kg. The photopic ERGs were evoked to 12 different intensities ranging from 0.81 to –2.19 log cd.s/m² and presented under photopic conditions in order to assess (from the derived luminance-response curves) Vmax and b : a amplitude ratio parameters. Photopic flicker ERGs were obtained at 30 Hz. The scotopic ERGs (intensity: –3.09 log cd.s/m²) were recorded while the retina was dark-adapting and after 32 min of dark adaptation. This procedure was performed on two separate sessions: following a 3-day interruption of LTh treatment (S1) and following 30 days without interruption of LTh treatment (S2). Results The mean photopic a-wave peak times were 9.8 ms at S1 and 5.0 ms at S2, respectively. The mean photopic b-wave peak times were 23.3 ms at S1 and 11.5 ms at S2, respectively, and the mean scotopic b-wave peak times (after 32 min of dark adaptation) were 45.2 ms at S1 and 26.0 ms at S2, respectively. No other significant ERG changes were observed. Conclusion Our results indicate that a dose of 20 µg/kg of LTh given to adult dogs was accompanied by a marked peak time shortening of both photopic and scotopic ERGs, without affecting other ERG parameters.  相似文献   

MENINGEAL ENHANCEMENT ON MAGNETIC RESONANCE IMAGING IN 15 DOGS AND 3 CATS     

Linda M.  Mellema  DVM  Valerie F.  Samii  DVM  Karen M.  Vernau  DVM  Richard A.  Lecouteur  BVSC  PhD 《Veterinary radiology & ultrasound》2002,43(1):10-15

A retrospective study of 15 dogs and three cats was done to characterize the appearance of meningeal enhancement on magnetic resonance (MR) images of the brain, and to correlate this appearance with its underlying cause. Two patterns of meningeal enhancement (pial and dural) were identified. Enhancement of the pia mater was evident in four dogs and one cat, while enhancement of the dura mater was seen in 11 dogs and 2 cats. A variety of causes of meningeal enhancement were identified, including bacterial and cryptococcal meningitis, plasmacytic meningitis with associated subdural fluid accumulation, granulomatous meningoencephalomyelitis, inflammation secondary to otitis interna, feline infectious peritonitis, and neoplasia. The present study confirms that pial or dural meningeal enhancement may be present on MR images of the brain of dogs or cats in association with a variety of central nervous system diseases. A larger prospective study is required to further establish the incidence of specific patterns of meningeal enhancement seen in association with specific diseases.  相似文献

LIU Guifang  TIAN Fayi 《中国畜牧兽医》2007,47(11):3774-3782

To determine the pathogen and related symptoms caused by renal failure,and to provide a reasonable diagnosis and treatment plan,a case of disease on Welsh Corgi dog was tested by the method of symptoms,blood routine examination,blood biochemical test,blood gas analysis and identification of pathogen.The results showed that these data of W-SCR,W-MID,MID and RDW-CV rose than normal reference index in blood routine examination before the hospitalization,respectively.Meanwhile,data of W-LCR,PCV,MCV,MCH and RDW-SD had reduced separately.These data of Ca²⁺,GLU,BUN,PHOS,AMYL and CRE were up than normal reference index in blood biochemical test,respectively.These data of GLU,BUN and K⁺ had risen respectively,nevertheless,these data of Na⁺,Cl^- and PCO₂ had lowered separately.The result was positive by the antigen testing with the Leptospira detector plate.After treatment with synthetical therapy,WBC and SCR had risen than normal references index,and data of RBC,HGB and PLT were down respectively.By the Hotelling T² analysis of the difference between before and after the therapy on blood routine index,it was significant difference in the multivariate test (F=1 905 045.32,P=0.001).These data of WBC,W-LCR,SCR,MID,HGB,PCV,MCV and RDW-SD were extremely significant differences in single variable analysis (P<0.01),and other data with significant differences were W-MID,RBC,MCH and PDW(P<0.05).But,in blood biochemical test,most of data were in normal reference values.The mental state of sick dog was recovering gradually normal than before.Multivariate test was no significant difference by the Hotelling T² analysis (F=85.21,P=0.081),but other data of GLU,BUN,PHOS,AMYL and CRE were extremely significantly different in single variable analysis (P<0.01).These data of GLU,BUN and K⁺ were up than after therapy in blood gas analysis,and data of Na⁺,Cl^- and PCO₂ reduced respectively.There were extremely significant differences in the multivariate test (F=7 978.48,P=0.008).These data with extremely significant differences were GLU and BUN in single variable analysis(P<0.01).The sick dog was recovering normal after treatment,and mental state went back to normal after 7 days therapy using the drugs of diuretics,antibiotics,rehydration electrolyte,energy medicine,vitamins and CoA.It should be noted that the part of high index of reexamination was a normal manifestation when the body was recovering to normal functioning.The method of synthetical fluid therapy was provided the correctness to treat the renal failure caused by canine Leptospira.  相似文献   

COMPARATIVE PERFORMANCE OF RADIOGRAPHY AND COMPUTED TOMOGRAPHY IN THE DIAGNOSIS OF MIDDLE EAR DISEASE IN 31 DOGS     

JACOB J. ROHLEDER  JERYL C. JONES  ROBERT B. DUNCAN  MARTHA M. LARSON  DON L. WALDRON  TONYA TROMBLEE 《Veterinary radiology & ultrasound》2006,47(1):45-52

The purpose of this study was to compare computed tomography (CT) and radiography for diagnosing the presence and severity of middle ear disease in dogs with a history of chronic otitis externa. Thirty-one dogs undergoing a total ear canal ablation and bulla osteotomy were studied. Three normal dogs served as controls. All dogs were examined using radiography and CT. Three radiologists independently evaluated imaging studies in random order. A visual analog scale method was used for scoring certainty and severity of middle ear disease. Surgical findings were recorded intra-operatively. Bulla lining samples were submitted for histopathologic evaluation and scored by a single pathologist who also used a visual analog scale system. Findings from both imaging modalities agreed more closely with surgical findings than with histopathologic findings. With either surgical or histopathologic findings as the gold standard, CT was more sensitive than and as specific as radiographs for predicting presence and severity of middle ear disease. Observer performance with CT was more consistent than the performance with radiographs in the detection of changes that occur with middle ear disease. Both radiography and CT were more accurate for predicting the severity of the disease than its presence. Findings indicate that CT is more accurate and reliable than radiography in diagnosing middle ear disease for dogs having concurrent otitis externa, but only when severity of disease is moderate or high. With low severity of disease, diagnostic certainty for both modalities becomes more variable.  相似文献
