Associations between the radiographic appearance of vascular channels in proximal sesamoid bones, their microstructural characteristics and past racing performance in Thoroughbreds.

Background: Abnormalities in vascular channel appearance within the proximal sesamoid bone (PSB) are the most common findings in Thoroughbred yearling presale radiographs and are often evaluated on radiographs of adult racehorses. Despite this, their pathogenesis and clinical significance are poorly understood, and associations with racing performance are inconsistent.

Objectives: To determine microstructural characteristics of the PSBs associated with the radiographic appearance of vascular channels using microcomputed tomography (µCT) and to determine associations with past racing performance in mature horses.

Identification and prevalence of errors affecting the quality of radiographs submitted to Australian thoroughbred yearling sale repositories.

We aimed to identify common mistakes made when radiographing yearling sale horses. Radiographic examinations from repositories at eight yearling sales held in Australia in 2003 were assessed by one of four veterinary radiology specialists. Each radiographic examination consisted of a maximum of 34 radiographs.

In vitro evaluation of feline leukocytes radiolabeled in whole blood with 99mTc stannous colloid.

Technetium-99m stannous colloid (9mTcSnC) has been used to radiolabel human leukocytes to investigate various inflammatory disorders. We investigated the in vitro behavior of feline leukocytes labeled in whole blood with 99mTcSnC. Heparinized blood samples were collected from healthy cats and divided into control and test aliquots.

Biodistribution of canine leucocytes labelled with technetium-99m stannous fluoride colloid in whole blood and their ability to localise to sites of induced inflammation.

This study assessed the biodistribution of autologous leucocytes radiolabelled with technetium-99m stannous fluoride colloid (99mTcSnC) for detection of foci of induced inflammation in dogs. Venous blood was collected from seven healthy dogs and incubated with 99mTcSnC for 1h at room temperature. Radiolabelled samples were injected intravenously (IV) and the dogs were scanned using a gamma camera.

In vitro evaluation of canine leukocytes radiolabeled in whole blood with (99m)Tc stannous colloid.

Introduction: Technetium-99m stannous colloid ((99m)TcSnC)-labeled leukocytes are used to investigate a variety of inflammatory diseases in human medicine. The present study investigates the in vitro behavior of canine leukocytes labeled in whole blood with (99m)TcSnC.

Methods: Blood samples from 10 healthy dogs were labeled with (99m)TcSnC using a standard procedure.
