Figure 8.

(a) Photograph of round-shaped, mass-like simulating lesion (sphere internal diameter=10 mm). The three tubes toward the right connect the lesion with the phantom jar lid and allow for filling of the lesion with contrast agent as well as future dynamic contrast agent experiments. (b) Photograph of lobular-shaped, masslike simulating lesion (3 lobulations plus 10 mm internal diameter sphere diameter). (c) Fat-suppressed, T₁-weighted, gradient-echo image (0.75 mm isotropic resolution, coronal slice) of a complete phantom with the round-shaped simulating lesion inserted and filled with gadolinium-doped water. (d) The same as (c) with the lobular-shaped simulating lesion.
