To describe magnetic resonance imaging (MRI) anatomy of the ovine stifle and investigate meniscotibial and cruciate ligaments anatomy.
Descriptive ex vivo study.
Pelvic limbs (n = 44) from 22 adult Texel ewes.
Forty limbs (n = 40) were scanned using 3 Tesla MRI before gross anatomic dissection. Two other limb pairs were frozen and transected to obtain sections that were compared with MRI images for identification of anatomic structures.
In all stifles, the craniomedial bundle of the cranial cruciate ligament inserted caudally to the cranial attachment of the medial meniscus. No transverse intermeniscal ligament was identified in 80% of stifles, whereas a few small ligamentous fibers were seen crossing from 1 cranial horn to the other in 20% of stifles. There was good differentiation of menisci, ligaments, and synovial cavities on MRI images. Two bundles were identified in all cranial cruciate ligaments on MRI. Sensitivity and specificity of 3T MRI for detection of transverse intermeniscal ligament were 42% and 84%, respectively.
3T MRI provided well defined reference images for menisci, synovial cavities, and most ligaments.
描述绵羊膝关节的磁共振成像（MRI）解剖结构，并研究半月板胫韧带和交叉韧带的解剖结构。
描述性离体研究。
来自22只成年特克塞尔母羊的骨盆肢体（n = 44）。
在大体解剖前，使用3特斯拉MRI对40个肢体（n = 40）进行扫描。另外两对肢体被冷冻并横断以获取切片，将其与MRI图像进行比较以识别解剖结构。
在所有膝关节中，前交叉韧带的颅内侧束插入到内侧半月板颅侧附着点的尾侧。80%的膝关节未发现半月板横韧带，而20%的膝关节可见一些小的韧带纤维从一个颅侧角交叉到另一个颅侧角。MRI图像上半月板、韧带和滑膜腔有良好的区分。MRI上所有前交叉韧带均识别出两束。3T MRI检测半月板横韧带的敏感性和特异性分别为42%和84%。
3T MRI为半月板、滑膜腔和大多数韧带提供了清晰的参考图像。
