Nine cadaver limbs were acquired from clinically normal horses.
Stifles were evaluated ultrasonographically and then by an extensive 1.5 T MRI protocol.
Subsequently, all stifles were evaluated for gross pathologic change.
Findings were compared between gross evaluation and MRI imaging and described.
No soft tissue structure abnormalities were identified on any evaluation.
Specific descriptive findings of the meniscotibial, meniscofemoral, collateral, patellar and cruciate ligaments, and the menisci were reported.
The high field MRI protocol described in this study provided high spatial and contrast resolution of the soft tissue structures, and this in turn allowed visualization of detailed structural characteristics, such as striations and variations in signal intensity.
Findings supported the use of high field MRI as a modality for the evaluation of the soft tissues of the equine stifle.
As clinical availability of this modality increases in the future, authors anticipate that new stifle diseases will be detected that have not previously been identified with other imaging modalities.
