The canine species is commonly used as a preclinical
model and understanding the normative and compartment
dependent T2 values of the canine knee will be
beneficial for longitudinal evaluation of
osteoarthritis. T2 mapping was performed on the stifles
of 7 dogs to evaluate the articular cartilage of the
femoral trochlea, patella, femoral condyles, and tibial
plateau. Differences of cartilage T2 values were found
throughout the stifle joint with the lateral femoral
condylar having the longest T2 values compared to the
other regions of interest. The results provide a
baseline of normative values for researchers in future
preclinical studies.
