Veterinary medicine has come a long way in recent years, with advancements in technology and imaging techniques leading the way in improving the diagnosis and treatment of animal health issues. Among these imaging techniques, computed radiography (CR) has proven to be an essential tool in veterinary medicine, from diagnosing fractures in racehorses to detecting dental problems in companion animals.
This imaging technique uses a reusable imaging plate to create digital images of animal anatomy, allowing for detailed and accurate visualization of bones and other structures. Compared to traditional film-based radiography, CR provides superior image quality, lower radiation exposure, and faster image acquisition times.
This blog will explore in-depth why computed radiography is essential in veterinary medicine, from its applications in equine and small animal medicine to its benefits over traditional film-based radiography.
Introduction to Computed Radiography
Computed Radiography is an imaging technique that uses a photostimulable phosphor plate to create digital images of anatomical structures. The technique is based on the same principles as traditional X-Ray imaging, but instead of capturing the X-Ray image on film, it captures the image on a reusable imaging plate.
The imaging plate used in CR is made of a material that can absorb X-Rays and store the energy as trapped electrons. When the plate is exposed to X-Rays, the trapped electrons are released, and the plate emits visible light in proportion to the amount of X-Ray energy absorbed. The emitted light is then captured by a photodetector and converted into a digital signal that is processed by a computer to produce an image.
According to the BIS Research report, the global industrial computed radiography market is estimated to reach $68.8 million in 2033 from $59.1 million in 2022, at a growth rate of 1.49% during the forecast period 2023-2033.

Importance of Computed Radiography in Veterinary Medicine
Computed Radiography (CR) has become an essential tool in veterinary medicine due to its ability to provide detailed and accurate images of animal anatomy, allowing for the early detection and diagnosis of health issues in animals. Here are some reasons why computed radiography is essential in veterinary medicine:
Accurate Diagnosis of Musculoskeletal Conditions: Equine athletes, such as racehorses, are prone to musculoskeletal injuries, which can be challenging to diagnose accurately. However, CR provides detailed and accurate images of bone structures, allowing veterinarians to identify fractures, soft tissue injuries, and other musculoskeletal conditions that may impact performance. Early detection and treatment can help horses recover quickly and prevent further damage.
Improved Dental Care for Small Animals: Dental problems are common in dogs and cats, and CR provides detailed images of the teeth and surrounding structures. By using CR, veterinarians can detect dental conditions such as tooth decay, periodontal disease, and oral tumors in their early stages. This early detection can help prevent tooth loss and other complications associated with advanced dental disease.
Lower Radiation Exposure: CR uses lower levels of radiation than traditional film-based radiography, reducing the risk of radiation exposure for both animals and veterinary staff.
Faster Image Acquisition Times: CR allows for faster image acquisition times, which is particularly important in emergency situations where time is of the essence.
Improved Image Quality: The digital images produced by CR are of higher quality and resolution than those produced by traditional film-based radiography. This allows for better visualization of anatomical structures, making it easier for veterinarians to diagnose and treat health issues.
Computed Radiography vs. Traditional Film-Based Radiography
Computed Radiography (CR) and traditional film-based radiography are both imaging techniques used in veterinary medicine to visualize internal structures and diagnose medical conditions. However, there are several differences between the two techniques. Here are some of the key differences between computed radiography and traditional film-based radiography:
Image Quality: Computed radiography produces digital images with higher resolution and greater clarity than traditional film-based radiography. This is because the digital images produced by CR can be manipulated and enhanced on a computer, allowing for better visualization of internal structures.
Processing Time: CR has a faster processing time compared to traditional film-based radiography, as the images are captured and stored digitally, eliminating the need for processing and development time associated with film-based radiography.
Environmental Impact: Computed radiography is considered more environmentally friendly than traditional film-based radiography, as it does not require the use of film and chemicals.
Radiation Exposure: Computed radiography involves less radiation as compared to conventional film-based radiography, thereby decreasing the possibility of radiation exposure for both the veterinary personnel and the animal.
Cost: The initial cost of setting up a CR system is higher than traditional film-based radiography. However, over time, the cost of using CR is lower as it eliminates the ongoing expenses of film and chemicals.
Portability: Traditional film-based radiography equipment is typically larger and less portable than CR equipment, which can make it more challenging to use in the field or in emergency situations.
Conclusion
With the ability to produce high-quality images in a shorter time frame, CR has become an essential tool for veterinarians in emergency situations and in situations where time is of the essence.
Additionally, the lower radiation exposure and reduced environmental impact associated with CR make it a more sustainable and safer option for animals and veterinary staff. As technology continues to evolve, it is likely that CR will continue to play an increasingly significant role in veterinary medicine.
