ACVR and ECVDI consensus statement for teleradiology.

Increased demand for the interpretation of diagnostic images by board-certified radiologists and profound advancements in technology have led to extremely rapid growth in the field of veterinary teleradiology over the past decade. The aim of this consensus statement is to provide a guideline for best practices for quality and safety in veterinary teleradiology. The statement addresses appropriate image acquisition and transmission, the creation of teleradiology submissions, quality control in teleradiology, and appropriate documentation of imaging reports, as deficiencies in any of these areas may directly affect the standard of patient care.

Dose-response relationship of ultrasound contrast agent in an in vivo murine melanoma model.

Many factors affect the sensitivity and reliability of tumor vasculature assessment at the small doses of contrast agent necessary for imaging mice. In this study we investigate the dose-response relationship of ultrasound contrast agent for a minimal exposure power Doppler technique (minexPD) in a murine melanoma model. K1735 murine melanomas grown in 25 C3H/HeN mice were imaged by power Doppler ultrasound using different doses of contrast agents, Optison(R) and Definity(R).

The antivascular action of physiotherapy ultrasound on murine tumors.

This study was aimed at determining if physiotherapy ultrasound (US) affected the fragile and leaky angiogenic blood vessels in a tumor. In 22 C3HV/HeN mice, a subcutaneous melanoma (K1735(22)) was insonated (1, 2 or 3 min) with continuous 1-MHz low-intensity (spatial-average temporal-average = 2.28 W cm(-2)), physiotherapy US.

Oxygen distribution in murine tumors: characterization using oxygen-dependent quenching of phosphorescence.

In the present work, a novel method for detecting hypoxia in tumors, phosphorescence quenching, was used to evaluate tissue and tumor oxygenation. This technique is based on the concept that phosphorescence lifetime and intensity are inversely proportional to the oxygen concentration in the tissue sample. We used the phosphor Oxyphor G2 to evaluate the oxygen profiles in three murine tumor models: K1735 malignant melanoma, RENCA renal cell carcinoma, and Lewis lung carcinoma.

Risk factors for recurrence of clinical signs associated with thoracolumbar intervertebral disk herniation in dogs: 229 cases (1994-2000).

Objective: To assess risk factors for recurrence of clinical signs associated with thoracolumbar intervertebral disk disease (IVDD) in dogs that had decompressive laminectomy without attempted prophylactic treatment of other disk spaces.

Design: Retrospective study.

Animals: 229 dogs.

Medical and behavioral surveillance of dogs deployed to the World Trade Center and the Pentagon from October 2001 to June 2002.

Objective: To evaluate early medical and behavioral effects of deployment to the World Trade Center, Fresh Kills Landfill, or the Pentagon on responding search-and-rescue (SAR) dogs.

Design: Prospective double cohort study.

Animals: The first cohort included SAR dogs responding to the September 11, 2001, terrorist attacks (deployed), and the second cohort included SAR dogs trained in a similar manner but not deployed (controls).

Otolithiasis in three dogs.

Mineral opacities within the tympanic bullae, termed otoliths, were detected in three dogs by means of radiography and computed tomography. Radiographic signs of otitis externa were present in two dogs. One dog had clinical signs of vestibular disease, whereas the other two dogs had no clinical evidence of ear disease.

Risk factors associated with development of seizures after use of iohexol for myelography in dogs: 182 cases (1998).

Objective: To determine prevalence of seizures after use of iohexol for myelography and identify associated risk factors in dogs.

Design: Retrospective study.

Animals: 182 dogs that received iohexol for myelography in 1998.
