In this study, we explored the combined use of magnetization transfer (MT) weighting and bi-exponential T2* fitting as a potential tool to analyze the composition and microscopic geometry of the knee cartilage. The analysis results of deep cartilage areas showed that the MT ratio of the short T2* component had significantly larger values than that of the long T2* component. This observation may be explained by the geometry of collagen fibrils and proteoglycans.
