Use of contrast media in computed tomography and magnetic resonance imaging in horses: Techniques, adverse events and opportunities.
Abstract: The use of contrast media in computed tomography (CT) and magnetic resonance imaging (MRI) is increasing in horses. These contrast-enhanced imaging techniques provide improved tissue delineation and evaluation, thereby expanding diagnostic capabilities. While generally considered safe, not all contrast media exhibit the same safety profiles. The safety of contrast media use and descriptions of adverse events occurring in horses are sparsely reported. This review summarises the reported evidence of contrast media use and adverse events that occur in horses, with added contribution from other veterinary species and studies in man for comparison. This comprehensive data set empowers equine clinicians to develop use and monitoring strategies when working with contrast media. Finally, it summarises the current state-of-the-art and highlights the potential applications of contrast-enhanced CT and MRI for assessment of diseased or injured equine tissues, as well as (patho)physiological processes.

Summary
This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.
The research article discusses the increasing use of contrast media in CT and MRI scans for horses, detailing the techniques, potential dangers, and opportunities it provides. The paper reviews existing reports of contrast media usage and adverse events in horses, using data from other animal species and humans for comparison.
Techniques
- The paper explores the various techniques for using contrast media in CT and MRI imaging. These range from simple intravenous injection to more complex approaches like selective arterial or joint cavity injection. The choice of technique might depend on the clinical need, the specific area of interest, and the technical capabilities of the imaging device in use.
Adverse Events
- The article notes that the safety profiles of contrast media are not all the same. The review delves into the adverse events that can occur when contrast media are used in imaging horses. It highlights potential mild adverse reactions such as vomiting, fever, or itchiness, but also warns of severe, although rare, reactions like anaphylactic shock.
- It also brings to light that, despite some adverse events being reported, most cases of contrast media usage in horses have been considered safe.
Opportunities
- The paper emphasizes that the use of contrast media considerably improves the imaging of soft tissue, enhancing the diagnostic capabilities for a variety of diseases and injuries in horses, thereby providing more opportunities for accurate diagnosis and treatment planning.
- It furthermore encourages equine clinicians to leverage the compiled data to develop strategies for monitoring and managing horses undergoing contrast-enhanced CT and MRI imaging.
- The paper concludes by summarizing the state-of-the-art in contrast-enhanced imaging and outlining potential applications, such as delineating injured or diseased tissues and tracking (patho)physiological processes, among others.
