Abstract

The objective of this study was to define the normal gross anatomic appearance of the adult equine tarsus on a low-field magnetic resonance (MR) image. Six radiographically normal, adult, equine tarsal cadavers were utilized. Using a scanner with a 0.064 Tesla magnet, images were acquired in the sagittal, transverse and dorsal planes for T1-weighted and the sagittal plane for T2-weighted imaging sequences. Anatomic structures on the MR images were identified and compared with cryosections of the imaged limbs. Optimal image planes were identified for the evaluation of articular cartilage, subchondral bone, flexor and extensor tendons, tarsal ligaments, and synovial structures. MR images provide a thorough evaluation of the anatomic relationships of the structures of the equine tarsus.

摘要

本研究的目的是在低场磁共振（MR）图像上确定成年马跗关节的正常大体解剖外观。使用了六具X线摄影正常的成年马跗关节尸体。使用一台具有0.064特斯拉磁体的扫描仪，在矢状面、横断面和背侧平面采集T1加权图像，并在矢状面采集T2加权成像序列图像。识别MR图像上的解剖结构，并与成像肢体的冷冻切片进行比较。确定了用于评估关节软骨、软骨下骨、屈肌腱和伸肌腱、跗关节韧带以及滑膜结构的最佳图像平面。MR图像可对马跗关节结构的解剖关系进行全面评估。
