In this study we created normal T2 map profiles from the entire femoral cartilage of 20 healthy volunteer knees to assess regional variations using a novel angle/layer dependent approach. Overall, variations were observed in inter- and intra-rater reliability by location, and in T2 values by angular orientation to B0 and layers of the cartilage. The results indicate the importance of evaluating cartilage in consideration of these variations for diagnosis of cartilage degeneration in specific location of the knee.
