The Evolution of Animal Imaging (1980s–Today)

Over the last 40 years, veterinary medicine has quietly transformed.

Not because of new pills or surgeries, but because we can now see what used to be hidden in pet health. From blurry ultrasound pictures in the 1980s to today’s crisp MRI scans, diagnostic imaging has changed how we find and treat disease in animals. 

But this evolution is more than just the latest technology. It’s the adoption of forward-thinking business models–and above all: the belief that pets deserve the same high-quality care as people.

At Sage Veterinary Imaging (SVI), we use ultrasound, CT, and MRI to deliver fast, detailed answers that help you have peace of mind when it comes to your furry friends.

Here’s a look at how it all started, and where we’re headed as experts in veterinary imaging and stewards of your pet’s health.

1980s: The Age of Limited Access

In the early 1980s, diagnostic imaging in veterinary medicine was still largely limited to radiographs (X-rays). Ultrasound was just beginning to emerge as a tool in academic settings, but its availability in general practice was rare.

  • Ultrasound units were big, expensive, and not very clear. Most general practices didn’t have access to them.

  • MRI and CT were only found in human hospitals. Vets had to work with teaching hospitals to use them, and even then, it wasn’t easy.

  • Diagnosing many internal problems felt like guesswork. Vets had to rely on symptoms and hunches. Sometimes, the only way to know what was wrong was to do surgery and look inside.

Veterinary radiology was still considered a niche specialty, and the idea of advanced outpatient imaging was years away.

As technology became more portable and cost-effective, things began to change in the 1990s. Imaging machines got smaller, cheaper, and easier to use.

  • Ultrasound began to enter general practice, especially in large practices. Mobile services popped up, with sonographers visiting different practices.

  • CT scanners trickled into major academic and referral centers. They were mostly used for bones and sinuses, and even then, only in special cases.

  • Veterinary MRIs remained limited to academia.  Some animal hospitals tried using human machines after hours, but that brought challenges like safety and scheduling.

Meanwhile, pet owners were starting to ask more questions. They wanted answers. Vets felt the pressure to offer better diagnostics, just like doctors do for people.

2000s: The Rise of Advanced Diagnostic Imaging

By the early 2000s, veterinary medicine was stepping into a new chapter. Specialty hospitals were growing. More vets were becoming board-certified. And imaging became a must-have.

  • Mobile imaging services grew rapidly. Experts traveled with machines, helping clinics without their own equipment. The images definitely helped, but sometimes lacked the detail needed to see more complex disease.

  • Veterinary neurologists and surgeons began to require imaging before treatment. CT and MRI went from “nice to have” to “need to have.”

  • Veterinary-specific MRI and CT units entered the market. These were typically low-field MRI systems (0.2T–0.5T) and 8- to 16-slice CT scanners; smaller and less powerful than human versions, but they got the job done.

  • Referral hospitals consolidated diagnostic and treatment services under one roof. But this new model created significant bottlenecks, as imaging demand far outpaced capacity.

As more pets began receiving MRIs, neurologic and orthopedic diagnostics reached new levels of accuracy. But clients often waited days or weeks for access—and prices continued to climb.

In the 2010s, imaging demand exploded. But access didn’t keep up.

  • More specialists were using MRI. More pet owners were asking for it. But there just weren’t enough machines (or trained radiologists) to go around.

  • Many general practices still didn’t have advanced imaging in-house. They had to refer patients, which meant more delays, more cost, and more stress for clients.

  • Specialty hospitals became overwhelmed. Long waitlists. Overworked teams. Slower care.

That’s when Sage Veterinary Imaging was born.

In 2016, we began by offering mobile ultrasound to clinics across Central Texas, bringing high-quality imaging straight to the patient. By 2020, we opened our first outpatient imaging center, built to deliver same-day MRI and CT scans without the delays and complexities of a referral hospital. 

It was a new way forward: fast, clear answers that help veterinarians take action sooner.

Today, outpatient imaging is rapidly reshaping the veterinary landscape, just as it did in human medicine two decades prior.

  • SVI and other centers now offer same-day MRI and CT with 3T and 128-slice technology.

  • Pet owners can schedule directly or work through their family vet. Either way, the process is smooth and simple.

  • Reports are usually delivered within 24 hours, often the same day. That means vets can make quicker decisions and get pets on the path to treatment sooner.

  • Outpatient centers take pressure off emergency and specialty teams. That gives them more time to focus on surgeries, critical cases, and the pets who need them most.

The result is a more balanced, efficient veterinary care ecosystem where diagnostics are timely, high-quality, and integrated into the broader workflow of general practice and referral care.

The next chapter in veterinary imaging is already taking shape. At SVI, we’re embracing new tools and technologies that make care even better—for pets, vets, and families.

  • AI-assisted scan reading is getting smarter. It helps radiologists work faster and with greater accuracy, so results come back quickly and with confidence.

  • 3D and functional imaging are on the rise. These scans show what’s there and how it’s working, from blood flow to nerve function.

  • New tools will help pet owners see what we see. With clearer visuals and easier explanations, clients can better understand diagnoses and feel part of the care plan.

  • Diagnostic hubs will serve wider areas. Outpatient centers like ours will connect digitally with more clinics, helping pets get advanced care no matter where they live.

The future of imaging isn’t just faster and clearer; it’s smarter, more collaborative, and more integrated into everyday practice.
