Standing magnetic resonance imaging (MRI) and computed tomography (CT) offer advanced diagnostic capabilities for equine patients. This review covers the practical aspects, benefits, and challenges of using these imaging techniques on standing horses for surgical case selection.
Area of Science:
- Veterinary Radiology
- Equine Diagnostic Imaging
- Advanced Imaging Modalities
Background:
- Clinical application of advanced imaging in equine medicine is expanding.
- Standing imaging techniques provide unique advantages for specific equine cases.
- Understanding the principles and limitations of MRI and CT is crucial for effective use.
Purpose of the Study:
- To review the clinical applications of standing magnetic resonance imaging (MRI) and computed tomography (CT) in horses.
- To discuss the logistics, benefits, drawbacks, and limitations of standing equine imaging.
- To guide the selection of appropriate clinical cases for standing MRI and CT.
Main Methods:
- Review of the physics principles of MRI and CT relevant to clinical practice.
- Discussion of hardware and software requirements for image acquisition and artifact reduction.
- Analysis of case selection criteria for standing imaging procedures.
Main Results:
- Standing MRI and CT offer viable alternatives to general anesthesia for equine imaging.
- Successful application depends on careful patient selection and understanding of technique limitations.
- These modalities facilitate diagnosis in horses suitable for standing surgery.
Conclusions:
- Standing MRI and CT are valuable tools in equine diagnostic imaging.
- Proper case selection and technique are key to maximizing diagnostic yield and patient safety.
- These imaging methods support surgical planning for specific equine conditions.
