Gathering vital patient information with ultrasoundMay 27, 2019Anthony J. Fischetti, DVM, MS, DACVR, department head of diagnostic imaging at the Animal Medical Center in New York, had just finished his shift. It had been an odd day; two dogs that had turned yellow had been brought into the clinic. The first patient, an older dog, had a tumor at the entrance of the gall bladder into the intestines—a common bile duct obstruction. The second patient had collapsed, experiencing diarrhea and vomiting. "I used the ultrasound to diagnose that it wasn't the liver," said Dr. Fischetti. "It turned out the dog was hemolyzing." An old, corroded coin in the dog's stomach was causing zinc toxicity. Thanks to the ultrasound images, the endoscopist retrieved the coin and the dog improved. Fischetti, who also is president of Veterinary Ultrasound Society of the American College of Veterinary Radiologists (ACVR), as well as other experts, say ultrasound is a safe and simple way to get more information on ailing patients. "I think the real value of ultrasound is its noninvasive nature," said Nathan C. Nelson, DVM, MS, DACVR, a clinical associate professor of radiology at the North Carolina State University College of Veterinary Medicine. Why use ultrasound? Key considerations for adding …

CT or MRI? When to use each and whyMarch 15, 2019Use MRI for meningitis, encephalitis, fibrocartilaginous embolism, malignancy of liver tumors, muscle tears and strains, and cranial cruciate rupture, says Tony Pease, DVM, MS, DACVR, chief veterinary medical officer of the Western Veterinary Conference Oquendo Center in Las Vegas, Nev. For fragmented medial coronoid processes, dental disease, 3-D reconstructions, and small bone fractures, use CT, he advises. "In general, MRI can see more medically treated lesions, but CT and MRI can see lesions that are amenable with surgery," Dr. Pease says. "However, gastrointestinal lesions are questionable. The motion of the gastrointestinal tract makes large artifacts, as does metal (e.g. microchips), which is not a factor with CT as opposed to MRI." MRI is preferred whenever disease of the central nervous system is suspected, says Nathan C. Nelson DVM, MS, DACVR, clinical associate professor of radiology at the North Carolina State University College of Veterinary Medicine. "MRI has excellent ability to image soft tissue structures and is able to differentiate gray matter, white matter, nerves, and cerebrospinal fluid to a much greater extent than CT," Dr. Nelson says. "In any case, where brain disease is suspected—such as the acutely seizing dog or the dog with sudden behavior change—MRI is the …

VolitionRx tests nucleosome diagnostic for veterinary space applicationsOctober 5, 2018 VolitionRx Ltd., a multinational Belgium-based life sciences company with offices in Texas, London, and Singapore, announced it is entering the veterinary market after "very encouraging" preliminary results from a study using its NuQ diagnostic blood tests for canine cancer testing. NuQ, currently used to screen for colorectal and prostate cancers, works by measuring and analyzing irregular levels of nucleosomes—a section of DNA wrapped around a core of proteins—in the blood to identify cancers. According to the company, the proof-of-concept study showed that blood nucleosomes also can be detected in dogs. With the promise of veterinary medicine applications, VolitionRx said it will now move NuQ into larger trials to answer the question of whether the method will work with animals. The company said it intends to outsource much of the veterinary clinical trial work through a partnership with Heather Wilson-Robles, DVM, DACVIM, associate professor and Fred and Vola N. Palmer chair in comparative oncology with Texas A&M College of Veterinary Medicine & Biomedical Sciences in the Small Animal Clinical Sciences department. "The Texas A&M University College of Veterinary Medicine Oncology Department is excited for the opportunity to collaborate with Volition," said Dr. Wilson-Robles. "Its innovative work in …
