ABSTRACT:
A probe (3) for use in in vivo imaging of a microscopic internal region (1) of a patient's body using magnetic resonance techniques incorporates a member (7) having a surface having a pattern of projections (9) formed thereon. In use the surface contacts the surface of the region to trap between the projections molecules in the region, thereby to restrict diffusion of the molecules and so improve resolution of the image obtained.
