How ultrasound became a core tool in veterinary medicine: full analysis

Ultrasound’s evolution in veterinary medicine is no longer just a story about better machines. It’s a story about how imaging moved closer to the patient, into more exam rooms, treatment areas, and emergency bays, while raising new questions about training, standards, and scope. A recent Veterinary Practice News article argues that the field’s progress has come from pairing technical advances with clinical judgment and thoughtful integration, not from equipment alone.

That framing fits the longer arc of veterinary ultrasound. A 2006 review in The Veterinary Journal noted that ultrasound was first used in animals for back-fat measurement tied to carcass quality, then expanded into routine small animal and equine diagnostic workups across cardiac, thoracic, abdominal, reproductive, ocular, and musculoskeletal applications. Over time, improvements in computing power and miniaturization changed what was possible in practice, helping move ultrasound from a specialized modality toward broader day-to-day use. A later review described sonography as an essential imaging modality in small animal medicine, with a history nearly as long as diagnostic medical sonography in human care. (sciencedirect.com)

The current phase of that evolution is defined by portability and focus. Veterinary Practice News points to high-frequency linear probes, easier digital storage, and the ability to share images for remote consultation as practical advances that have improved access and confidence. The article also emphasizes the growth of POCUS, especially AFAST and TFAST, which allow clinicians to evaluate unstable patients at the bedside without transport and to quickly identify problems such as free abdominal fluid, pericardial effusion, or urinary obstruction. That mirrors broader activity in the field: the International Veterinary Point-of-Care Ultrasound Society now explicitly positions VPOCUS and FAST ultrasound as tools to answer urgent clinical questions within minutes and help teams choose the next best diagnostic step.

The profession has also been shaped by educators and specialists who helped build ultrasound into mainstream veterinary imaging. Tufts’ Dominique Penninck, recently recognized in Tufts’ 2026 commencement materials as Professor Emerita, has focused her research on small animal abdominal ultrasonography and ultrasound-assisted interventional procedures. Her career has included clinical practice, ultrasound consulting, residency training, textbook chapters, and editorship of the Atlas of Small Animal Ultrasonography, illustrating how much the field’s growth has depended on mentorship and knowledge transfer, not just equipment upgrades.

Even with wider adoption, expert bodies are drawing a clear line between access and expertise. ACVR says ultrasound is the imaging modality of choice for many conditions, but stresses that interpretation is highly dependent on the operator’s training and skill. Its position statement says veterinarians performing and interpreting ultrasound should understand indications, limitations, anatomy, alternative diagnostics, image acquisition, documentation, and reporting. ACVR also notes that approved radiology residencies require substantial ultrasound-specific training, including at least 1,000 examinations, while technicians performing studies should work under strong supervision and mentorship. Separately, a 2022 ACVR/ECVDI consensus statement on abdominal ultrasound, summarized by Iowa State’s Kristina Miles, aimed to reduce variation in exam quality and documentation and described a full comprehensive ultrasound exam as the basic standard of care, while specifically excluding POCUS from that document’s scope.

Industry and academic commentary points in the same direction: ultrasound is expanding, but safe growth depends on structure. The Veterinary Practice News overview says POCUS can be especially useful for clinicians with less extensive training because it is limited and question-driven, and can help determine whether referral is needed. Earlier reporting from the same outlet quoted ACVR president Tony Pease on ultrasound’s ability to provide real-time information that other modalities may miss, and described rising demand that may be outpacing boarded radiologist capacity in some settings. In parallel, recent literature in Frontiers in Veterinary Science described ultrasound as an increasingly robust and beneficial diagnostic tool across veterinary practice. Taken together, that suggests a field that is broadening quickly, while relying more heavily on teleconsultation, selective referral, and tiered use models. (veterinarypracticenews.com)

Why it matters: For veterinary professionals, ultrasound’s evolution is changing both clinical expectations and practice operations. More teams can now perform focused bedside scans, communicate findings to pet parents in real time, and decide faster whether a patient needs surgery, referral, monitoring, or another imaging modality. But the expansion of access also increases the importance of defining what counts as a focused screening exam versus a comprehensive diagnostic study, how images are archived and reviewed, and when specialist input is needed. In other words, ultrasound is becoming more available, but not simpler. The practical challenge for clinics is building protocols, training, and quality controls that match the level of scan being offered. (veterinarypracticenews.com)

What to watch: The next chapter will likely focus less on whether practices have ultrasound and more on how they use it: broader POCUS education, clearer standards for comprehensive exams, more cloud-based image sharing, and continued collaboration between general practitioners, emergency clinicians, and boarded imagers. If those pieces keep maturing together, ultrasound’s role in veterinary medicine will keep expanding without losing diagnostic rigor. (acvr.org)
