Multiparametric MRI and Computational Modelling in the Assessment of Human Articular Cartilage Properties: A Comprehensive Approach

Figure 5

Correlation plots of mean relaxation times and the FF (a), CO (b), and PG (c) volume fractions and the fiber orientation (d) on a per-pixel basis. Regional evaluation was performed for the peripheral region (PR, orange) and the central region (CR, blue). Read plots as follows: An individual data point indicates a single pixel’s modelled quantity of the tissue property and the respective relaxation time. Of note, the fiber orientation angles are given with respect to the cartilage normal.
