摘要

随着磁共振成像技术在兽医学中的应用,磁场强度的重要性将继续成为争论的焦点。本文讨论了高场和低场磁共振成像系统之间的基本区别。讨论了磁体和房间结构、检查时间、图像质量以及对诊断准确性的影响。虽然许多损伤可以用高场和低场系统很好地表征,但需要高场系统来识别某些病变。需要进一步的研究来确定在高场和低场磁共振成像系统上病变可探测性的差异。

Magnetic Resonance Imaging of the Equine Patient: A Comparison of High- and Low-Field Systems

As use of magnetic resonance (MR) imaging evolves in veterinary medicine, the importance of field strength will be a continued source of debate. This article addresses the fundamental differences between high- and low-field MR imaging systems. The magnet and room construction, examination time, image quality, and implications on diagnostic accuracy are discussed. Although many injuries can be well characterized with both high- and low-field systems, a high-field system is required to identify certain lesions. Further studies are needed to define the difference in the detectability of lesions on high-field versus low-field MR imaging systems.
