Figure 1
Figure 1 A 45-year-old male rheumatoid arthritis synovium shows strong enhancement on fat suppressed post-contrast T1-weighted axial image. Color coded fractional anisotropy (FA = 0.26) map from segmented region of enhanced synovial membrane overlaid on post-contrast fat-suppressed T1-weighted image show increased FA as compared to control (FA = 0.19). Mean diffusivity being inversely related to FA showed low values (1.01 × 10-3 mm2/s). Color red denotes increased whereas blue denotes decreased values. RA: Rheumatoid arthritis; MD: Mean diffusivity; FA: Fractional anisotropy.
