Figure 24a — Comparison of sagittal 3D SPGR MR images obtained at 3.0 T (a) and 7.0 T (b) in the knee of a healthy volunteer shows no substantial difference in the appearance of the articular cartilage, although magnetic susceptibility artifacts are exacerbated at the higher field strength in tissues such as trabecular bone (arrowheads in b).
