Blastomycotic osteomyelitis associated with severe lameness in a horse     

Méndez-Angulo JL  Swaab ME  Malone E  Olson EJ  Chalkley MD  Aird B  Ward C 《The Canadian veterinary journal. La revue veterinaire canadienne》2011,52(12):1303-1307

A 12-year-old Quarter horse gelding was presented for evaluation of severe right forelimb lameness, 2 draining tracts over the lateral aspect of the right proximal antebrachium, and weight loss. A presumptive diagnosis of blastomycotic osteomyelitis was established based on radiographs and cytology of the exudate. This diagnosis was confirmed at necropsy.  相似文献

CONTRAST ENHANCEMENT IN MAGNETIC RESONANCE IMAGING USING INTRAVENOUS PARAMAGNETIC CONTRAST MEDIA: A REVIEW     

Igor V.  Kuriashkin  MD  PhD  John M.  Losonsky  MS  DVM 《Veterinary radiology & ultrasound》2000,41(1):4-7

Interest in magnetic resonance (MR) imaging as a major diagnostic tool in veterinary clinical medicine is increasing. Most MR studies are performed with the use of contrast enhancement via intravenous injection of paramagnetic gadolinium-containing contrast media. A vast number of publications are available regarding the use of contrast media in humans. The purpose of this paper is to assist practicing veterinary radiologists in understanding mechanisms of MR contrast enhancement. This paper reviews certain aspects of MR contrast enhancement, including physical, chemical and biologic characteristics of most common MR contrast media targeted primarily at the central nervous system (CNS). Authors also describe processes that explain changes in signal intensity on the MR images.  相似文献   

MAGNETIC RESONANCE ARTHROGRAPHY OF THE CANINE STIFLE JOINT TECHNIQUE AND APPLICATIONS IN ELEVEN MILITARY DOGS     

Catherine M.  Banfield  DVM  MS  William B.  Morrison  MD 《Veterinary radiology & ultrasound》2000,41(3):200-213

The stifle joints of eleven military working dogs were evaluated using conventional magnetic resonance (MR) imaging and MR arthrography. A protocol optimizing MR imaging of the canine stifle joint is discussed, as well as potential uses for administration of intra-articular gadolinium. The technique for performing MR arthrography is described, and post-contrast image findings are reviewed. MR arthrography was performed by using an intra-articular injection of diluted gadolinium. Consistently good quality images were obtained, and no complications were clinically detected following MR arthrography. Cranial cruciate ligament abnormalities were seen in six dogs, meniscal abnormalities were visualized in nine menisci, and synovitis and medial ligament strain were seen in eight dogs. Surgical and post-mortem confirmation of these findings is discussed in seven dogs. Although MR arthrography adds an invasive procedure to conventional MR imaging, it can provide useful information on pathologic changes in the canine stifle joint.  相似文献   

MAGNETIC RESONANCE IMAGING OF THE NORMAL AND DISEASED FELINE MIDDLE EAR     

Ingrid  Allgoewer  DVM  Susanne  Lucas  DVM  Stephan Albert  Schmitz  MD 《Veterinary radiology & ultrasound》2000,41(5):413-418

The magnetic resonance imaging appearance of the feline middle ear is described in three healthy cats and in five cats with middle ear disease. Owing to the good spatial resolution, multiplanar slice orientation as well as display high contrast resolution of soft tissue, in particular fluids, MR imaging was helpful prior to surgery. It is superior to radiography which failed to allow identification of the abnormality in two of our five cats. MR imaging for middle ear disease should include dorsal and transverse plane images using T1- and T2-weighted sequences. In the presence of a mass within the bulla or the external ear canal application of contrast medium is helpful.  相似文献

Implantation of an Uncemented Total Hip Prosthesis Technique and Initial Results of 100 Arthroplasties     

DAVID J. DeYOUNG  DVM  Diplomate ACVS  Diplomate ACVA  BONNIE A. DeYOUNG    HAROLD A. ABERMAN DVM  MSE    ROBERT V. KENNA  DAVID S. HUNGERFORD MD 《Veterinary surgery : VS》1992,21(3):168-177

A porous-coated modular total hip system was developed for uncemented implantation in dogs. The operative technique was developed in cadaver bones and live animals. One hundred uncemented total hip arthroplasties were performed in 92 dogs. Results were successful in 98% of the joints during follow-ups of 3 months or more. Complications included three luxations of the prosthetic joint, two fissure fractures of the femoral cortex, and one complete displacement of the acetabular component from its bony bed. Four complications were resolved successfully.  相似文献   

VOLUMETRIC IMAGE PROCESSING FOR THREE-DIMENSIONAL DISPLAY OF THE SKELETAL ANATOMY OF THE SEA OTTER     

Michael K.  Stoskopf  DVM  PHD  Elliot K.  Fishman  MD  Thomas D.  Williams  DVM 《Veterinary radiology & ultrasound》1990,31(3):142-145

Volumetrically correct, three-dimensional color images of the sea otter, ( Enhydra lutris ), were generated from computed tomographic (CT) data using a Sun 3/160 workstation and a Pixar Imaging Computer. These images could be displayed as static images (1024×768) or rotated about any axis in real-time by displaying sequential rotation sequences generated by the Pixar Imaging Computer. The images provided realistic depth of field through overshadowing and differential opacification. This was obtained through an opacification algorithm which traced rays from a selected viewing plane through colored gel volumes, and calculated absorbance percentages as a function of the transparency of the gels penetrated. Reconstructions of this type serve as alternative anatomy tutorials for species otherwise unavailable for routine dissection. They also permit topographical studies without interfering with populations of endangered animals.  相似文献   

Myasthenia Gravis in the Cat     

Richard J. Joseph DVM    Joseph M. Carrillo DVM  Vanda A. Lennon MD  PhD 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1988,2(2):75-79

Myasthenia gravis (MG) was diagnosed in four cats--one had an apparently congenital form and three had the acquired autoimmune form. All four cats were examined because of episodes of weakness including gait abnormalities, voice change, neck ventroflexion, and regurgitation. Palpebral reflexes were absent in all cats. Administration of edrophonium chloride resulted in transient resolution of clinical signs in all four cats. Three cats were tested for the presence of serum autoantibodies against acetylcholine receptor (AChR) by radioimmunoassay. Two cats with acquired MG had anti-AChR antibody titers of 10.5 and 96.8 nmol/l (normal, less than or equal to 0.03 nmol/l). Antibodies were not detected in the cat with presumptive congenital MG. All four cats were treated with pyridostigmine bromide. Two cats with acquired MG were euthanatized because of clinical deterioration. The third cat with acquired MG has been asymptomatic since 2 months after diagnosis. The cat with presumed congenital MG is alive 3 years after diagnosis.  相似文献
