Helical abdominal computed tomography (CT) was performed in nine normal beagle-mix dogs. Following cephalic vein injection of ionic iodinated contrast medium via power injector (rate 5 ml/s) dual-phase CT was performed in all dogs. A delayed scan was performed in five dogs between 5 and 13 min after the contrast medium injection. The median time of(More)
This article describes the findings in three dogs with histopathologically confirmed pancreatic insulinoma using dual-phase computed tomographic angiography (CTA). In all three dogs, dual-phase CTA findings identified lesions not seen on ultrasonography, including the actual identification of the primary pancreatic neoplasm in two dogs. CTA findings were in(More)
Helical computed tomography angiography was used to evaluate the renal vascular anatomy of potential feline renal donors. One hundred and fourteen computed tomography angiograms were reviewed. The vessels were characterized as single without bifurcation, single with bifurcation, double, or triple. Multiplicity was most commonly seen for the right renal vein(More)
OBJECTIVE To evaluate frequency, severity, and location of patellofemoral (PF) osteoarthritis (OA) in dogs with naturally occurring cranial cruciate ligament (CCL) disease. STUDY DESIGN Cross-sectional observational study. ANIMALS Dogs (n = 40; stifles, 44). METHODS Stifle arthroscopic video recordings and radiographs were performed. Cartilage(More)
The objectives of this study were to establish the sensitivity and negative predictive value of radiography for acute spinal osseous lesions in the canine trauma patient, and to evaluate the interobserver variability in radiographic assessment of the spine in traumatized dogs. This was a retrospective multiple observer blinded study. The study population(More)
CASE DESCRIPTION An 11-year-old spayed female Collie was evaluated because of regurgitation, dysphagia, severe ptyalism, coughing, and weight loss of approximately 12 weeks' duration. Esophageal squamous cell carcinoma had been diagnosed prior to referral on the basis of results of radiographic and endoscopic examination and histologic evaluation of biopsy(More)
Magnetic resonance imaging is used commonly to diagnose intervertebral disk herniation in dogs. It is common to locate areas of suspected compression on sagittal T2-weighted (T2-W) images and then obtain limited transverse images in these areas to reduce the acquisition time (a step-by-step approach). Our objective was to assess the frequency of correct(More)
OBJECTIVE To determine the sensitivity, positive predictive value, and interobserver variability of CT in the detection of bullae associated with spontaneous pneumothorax in dogs. DESIGN Retrospective case series. ANIMALS 19 dogs with spontaneous pneumothorax caused by rupture of bullae. PROCEDURES Dogs that had CT for spontaneous pneumothorax caused(More)
OBJECTIVE To describe the use and outcome of a single, simple continuous, barbed suture line for prophylactic, total laparoscopic gastropexy in dogs. STUDY DESIGN Multi-center, retrospective case series. ANIMALS Sixty-three client-owned dogs. METHODS Medical records of dogs undergoing total laparoscopic gastropexy using a barbed suture at 4 academic(More)
OBJECTIVE To describe proximal tibial metaphyseal fractures in immature dogs. MATERIALS AND METHODS Medical records of immature dogs with metaphyseal fractures of the proximal tibia were reviewed and data were collected on signalment and history of trauma. Craniocaudal and mediolateral radiographs were evaluated for the determination of the bones(More)
