Providing clinicians better guidance for treatment
Benefits of sMRI
More Accurate Diagnosis
Comprehensive MRI diagnosis allows you to evaluate the integrity of all the structures within a region, helping you make a more informed decision for treatment.
Informed Prognosis
Understand the full extent of the injury based on the degree of pathology in order to determine how aggressively you approach treatment.
Quick & Affordable Answers
Stop the guess work. Utilizing MRI as ‘first line’ imaging gets you an answer quickly and affordably. Protect the owner’s investment by definitively ruling out costly conditions that may not be causing any signs of lameness.
Visualize Tissues & Densities
Far beyond radiography, ultrasonography and even CT in some cases, standing equine MRI is capable of assessing both bony and soft tissue injuries with a single procedure.
Effectively Guide Treatment
MRI is accessible to a wide range of clients and patients and works best as an initial or ‘first line’ imaging modality to guide treatment decisions from the beginning of therapy and rehabilitation.
A Clear Picture of Chronic Lameness
MRI gives a clear picture to see what was missing and preventing the horse from regaining complete soundness.
Hallmarq’s Standing Equine MRI (sMRI) system brings the same diagnostic capability to equine clinical practice as human MRI with the patient at the forefront of every design
Quick, Safe & Convenient MRI
Advantages of sMRI
MRI Without Anesthesia
Standing MRI allows the procedure to be more convenient and cost effective, while at the same time reducing the risk of potential complications of general anesthesia such as colic and poor recovery.
Scan Multiple Regions
Standing MRI can be performed on multiple regions of the distal limb including the tarsus, carpus, metacarpus/metatarsus, flexor sheath, annular ligament, MCP joint, pastern joint, flexor tendons, distal sesamoidean ligaments, collateral ligaments, coffin bone, DIP, impar ligament, navicular bone and more.
True Diagnostic Quality
The diagnostic quality of standing (low-field) images has improved dramatically over the last 10 years. Standing equine MRI is now diagnostic in 90% of cases.
Radiologist Expertise
Radiologists are involved in the reading and reporting process whether remote or on-site. Radiologists have extensive experience with all types of MRI, both low- and high-field and are able to educate clinicians in development of scanning protocols to assure each anatomic region is appropriately imaged so nothing gets overlooked.
Convenience & Accessibility
With standing MRI, MRI no longer has to be reserved for advanced cases. Acute injuries where the lameness is localized to one region can benefit from an initial MRI to accurately guide therapy, saving costs on empirical treatments that may not be as successful as targeted treatments.
Offer the Gold Standard
The hassle of sending the horse hours away often prevents MRI from being a viable option. Investing in an MRI means investing in your client and patient base. Having MRI in-house allows you to not only offer your patients accurate diagnosis, but also positions you as a referral center.

Affordable, accessible, quick and convenient MRI
The process

Preparation
- General physical and lameness examination
- Removal of shoes (for imaging feet) on affected limb and contralateral limb for comparison and to avoid artifact.
- Radiographs – assure no nail clinches are left in the hoof that would create an artifact.

Sedation
- Many protocols and procedure options to fit your clinic
- Catheter or needle
- CRI or “topped off” as necessary
- Appropriate sedation typically achieved with alpha-2 agonists +/- opioid

Positioning
- Sedated and walked into MRI
- Lame leg usually positioned for scanning first
- Radiofrequency coil placed around area of interest
- Coil and magnet are both adjustable (within millimeters) to assure the region of interest is exactly in the middle of the scanning area of all 3 planes (x,y and z)

Scanning
- The first leg or region is scanned
- A set of pilot images are acquired to assure region of interest is located in the center of the magnet
- Multiple types of scans are set up in multiple planes to acquire all information about the region of interest
- Second leg or region is scanned

Post Scan Recovery
- Standing MRI makes outpatient visits possible
- The horse is placed in a stall or cross-ties to recover from sedation
- Generally, the horse can safely return home the same day

Diagnosis & Treatment
- Interpretation – Radiologists are available for consultation and official report distribution (usually within 24 hours)
- Consultation – Veterinarian and/or radiologist discuss the finding with the client
- Treatment – With a conclusive diagnosis more targeted therapies are recommended and more accurate prognosis is given
- Rehabilitation – Recommendations are provided to the client

FAQs
Much has been learned about the causes of equine lameness since the advent of MRI. From the previously under-diagnosed, such as collateral desmitis of the distal interphalangeal joint, through the previously misunderstood, such as navicular disease, to the previously unknown, such as bone marrow edema, MRI has revolutionized our ability to provide a diagnosis and improve prognosis in equine lameness.
MRI is unparalleled in providing images of both soft and bony tissues. Distinguishing water from fat, it highlights areas of pathology such as inflammation and bruising, in a way that radiography, CT, ultrasound or nuclear scintigraphy just can’t do. By imaging the region of interest in slices orientated in any 3D plane, a lesion can be visualized without superimposition of adjacent structures. Multiple views allow you to appreciate the full extent of the injury.
