Vetnuus |Oktober 2020 40 A British breakthrough in x-ray technology could soon offer practices 3D imaging without the expense and high radiation levels of a CT scanner. Adaptix Imaging, a tech start-up from Oxfordshire, has announced the latest trials of its 3D x-ray machine have proven the technology can work on sedated animals and could be ready to enter the veterinary market in the first half of next year. The x-ray machine being developed is around the same size as a computer printer and so, unlike a CT scanner, does not need a specialised room to be set aside. It sequentially takes 45 low-dose x-rays from slightly different angles, which, when combined, form a 3D image. Steve Wells, vice-president of technology at Adaptix Imaging, pointed out that the technology will never fully replace a CT scan for specialist surgery and inspecting soft tissue. However, he predicted the company’s machine will be a useful replacement for 2D x-ray machines because they will be available for comparable cost yet offer the benefit of 3D imaging. He said:“Our technology is an extension of the principle of two eyes giving you depth perception, which you don’t get with a flat, 2D x-ray. We believe it’s going to offer a cheaper, lower radiation path to 3D imaging than CT scans because you don’t need an adapted room with a reinforced floor, nor an upgraded power supply. It’s going to be roughly the same cost and radiation as a 2D X-ray. It will mean vets can take on a lot more of their imaging needs themselves without having to refer an animal to a facility with a CT scanner.” v (Source: www.vettimes.co.uk ) They also looked at risks of mixed-breed dogs developing cancers based on weight but found no increased risk in any weight category compared to intact dogs. The risk of joint disorders for heavier dogs can be up to a few times higher compared to dogs left intact. This was true for large mixed-breed dogs. For example, for female dogs over 43 pounds, the risk jumped from 4 percent for intact dogs to 10-12 percent if spayed before a year of age. NEUTERING POLICIES SHOULD BE REVIEWED "The study raises unique challenges," noted co-author Lynette Hart, professor at the UC Davis School of Veterinary Medicine. "People like to adopt puppies from shelters, but with mixed breeds it may be difficult to determine just how big the dog will become if you don't know anything about the dog's parents." Neutering prior to adoption is a common requirement or policy of humane societies, animal shelters and breeders. The authors suggested the policy be reviewed and modified appropriately. Shelters, breeders and humane societies should consider adopting a standard of neutering at over a year of age for dogs that will grow into large sizes. "They need to take a serious look at this," said Hart. "Joint disorders can shorten a dog's useful working life and impact its role as a family member." v (Source: www.sciencedaily.com ) Bits and Bobs I Stukkies en Brokkies Breakthrough 3D x-ray tech shows promise for practices Proof of concept imaging of a live cat.
