Veterinary MRI - Equine MRI

G-scan Equine MRI


Innovation, effectiveness and ease of use are the keywords for the
G-scan Equine.
G-scan Equine scanner represents one of Esaote’s most important developments in MRI technology.
G-scan Equine is a member of the Esaote dedicated MRI scanners family especially developed to address the veterinary market needs for horse examinations, plus the possibility to scan pets.
With respect to traditional MRI systems, thanks to rotating magnet G-scan Equine offers the capability to scan also the horse’s stifle, an anatomical region otherwise extremely hard to be imaged on any other MRI system on the market.
Furthermore, as with the Vet-MR Grande also the G-scan Equine provides easy accessibility for the operator, facilitating positioning and handling of the animal.
The specific dimensions of the system allow the use of standard available MRI compatible anaesthesia equipment.
The user interface has also been designed specifically for the “vet” setting featuring appropriate “vet” terminology.

G-scan Equine, the world’s first ROTATING Veterinary MRI scanner designed specifically for horses, providing a flexible solution to your equine imaging challenges.

  • Exquisite head, neck, limb and stifle images
  • Low-maintenance
  • Can be installed within an existing room
  • 220-volt power source

The system has been purposely designed for veterinary applications with veterinary software, terminology and image orientation. The system provides a wide range of pre-programmed protocols that are optimised for veterinary requirements. It also offers the possibility to create customised protocols, according to specific clinical needs.

The G-ScanVet Rotating System delivers superb diagnostic images to the practitioner who needs clear answers to problems in the foot, carpus, tarsus, hock, brain, sinus & neck with remarkable cost effectiveness and ease of use.

G-scan Equine shares the same examinable anatomies from Vet-MR Grande for horses (Fetlock, Hoof, Pastern, Hock, Carpus, Elbow, Neurocranium, Splanchnocranium) but makes Stifle examination feasible by placing the horse on his back and stretching his limb in the system’s isocentre

Some of the confirmed diagnoses available with MRI include the following:

  • Deep Digital Flexor Tears
  • Navicular Syndrome
  • Palmar Foot Pain
  • Bone Cysts
  • Bone Fractures
  • Lesions

The G-scan Equine has a wide opening; ensuring animal handling is extremely easy, even for very large animals.

Patient positioning is made easier and quicker because of the real-time imaging tool located on the front of the magnet. It produces instant images and continuously visualises the area of interest. This allows the user to ensure the position of the patient is optimal before starting the scan. 

The G-scan Equine can also be used as a small animal MRI system offering further flexibility of use.


The magnetic resonance system G-scan Equine is a scanner specifically designed for imaging horses thanks to the rotating magnet.
This unique feature, in fact, allows imaging also the horse’s stifle, an anatomical region otherwise extremely hard to be imaged on any other MRI system on the market.
Furthermore, as G-scan Equine shares the same user interface of Vet-MR Grande featuring appropriate “vet” terminology, it’s also possible scanning small animals.
G-scan Equine is very easy to install: even if it shall always be installed in a custom cage, a reasonable space required for installation is approximately 55 square metres. Anyway, Imotek can help you anytime with defining the most suitable site layout.
The complete system weights 7700 Kg and uses a maintenance free permanent magnet. Thanks to its low energy consumption, the system does not need any special power supply.
(For detailed installation specifications please refer to the site planning guide.)

• Radio frequency transmission coil
• Total weight of the magnetic unit is 6050 Kg
- Data control, imaging and display system including:

I5 processor @ 3.33 GHz or superior, 32 GB of memory RAM or superior, Control processor, 100 MIPS, 1,28 Mb Ram, Hard disk 1 Tera byte SSD or superior, CD DVD combo unit (CD - 7000 images at 256 matrix, DVD - 30.000 images at 256 matrix), Reconstruction times < 0,4 sec/image. For post-processing, the system is equipped with extensive image viewing, analysis and elaboration tools. G-scan Equine is based on the Windows 10 Enterprise Operating System which makes future enhancements and upgrades easy to implement.
2. Set of 4 high sensitivity receiving coils with automatic recognition that greatly speeds up and facilitate patient positioning; 3 coils are equipped with the Dual Phased Array (DPA) technology for optimal performances.
