Standing low-field MRI of the equine proximal metacarpal/metatarsal region is considered useful for diagnosing primary bone pathology and makes a positive contribution to case management: A prospective survey study.

Abstract: High-field MRI of the proximal metacarpal/metatarsal region has been associated with great diagnostic potential and clinical reports of standing low-field MRI of the forelimb suggest the same. To better understand diagnostic outcomes with standing low-field MRI of the proximal suspensory region, a prospective survey study was conducted and users of a widely available system questioned on their experience, operating procedures, and interpretation of standing low-field MRI findings. Response data included scores on a modified Likert scale from which weighted ratings were calculated for statistical analyses. Depending on the question, responses were obtained from 17 to 29 of the 38 invited facilities. Users indicated that standing low-field MRI was most frequently performed in the face of equivocal diagnostic findings; compared to Sports horses, general purpose riding horses were thought less likely to have detectable abnormalities and standing low-field MRI was rated most useful for the detection of primary bone pathology in the proximal metacarpal region. Standing low-field MRI signal change involving both the suspensory ligament and adjacent bone concurrently was rated most relevant and abnormalities solely affecting the muscle/adipose tissue bundles least relevant for diagnosing suspensory ligament injury. Transverse scans and in decreasing order T1-weighted gradient echo, short-tau inversion recovery FSE, T2*-weighted gradient echo, and T2-weighted FSE sequences were most frequently acquired and judged most useful by the majority of users experienced in imaging of the target area. This survey supports the relevant impact of standing low-field MRI on clinical case management, particularly in the context of imaging the proximal metacarpal region.

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 involves assessing the efficacy of standing low-field Magnetic Resonance Imaging (MRI) for diagnosing bone pathologies in the proximal metacarpal/metatarsal region of horses, and its impact on case management. The findings suggest that this technique is particularly valuable when other diagnostic results are ambiguous, and is especially effective for detecting primary bone pathologies alongside helping manage equine health cases.

Research Methodology

  • The study was a prospective survey engaging users of a prevalent standing low-field MRI system who regularly perform equine images.
  • The users shared their experiences, operating procedures, and interpretation methods of the MRI findings.
  • The collected data was rated on a modified Likert scale, and these scores were used to calculate weighted ratings for statistical analysis.
  • Between 17 to 29 facilities out of the invited 38 provided responses, depending on the query.

Key Findings

  • Survey results showed that standing low-field MRI was mostly used when other diagnostic results were implicative or unclear.
  • Compared to sports horses, general-purpose riding horses were less likely to have observable abnormalities.
  • Standing low-field MRI achieved high rankings for the detection of primary bone pathologies in the proximal metacarpal region of horses.
  • Abnormalities affecting both the suspensory ligament and the adjacent bone concurrently produced the most pertinent MRI signal changes for diagnosing a suspensory ligament injury.
  • On the contrary, abnormalities solely affecting muscle/adipose tissue bundles were found to be less critical.

Image Acquisition Techniques

  • Different scanning sequences like T1-weighted gradient echo, short-tau inversion recovery FSE, T2*-weighted gradient echo, and T2-weighted FSE were widely used, with transverse scans being the most common.
  • The users with extensive experience in imaging the target area deemed these sequences the most useful.

Impact on Clinical Case Management

  • The survey underscores the significant influence of standing low-field MRI in the management of equine clinical cases, primarily when it comes to imaging the proximal metacarpal region.
