The particular utility of NMR microscopy lies in the contrasts that are available. Image contrast in NMRI depends on material-specific parameters (spin-density and nuclear spin relaxation times), operator-related parameters (pulse sequence, pulse delay and repetition times) and external parameters (temperature, viscosity, etc.). Common contrast mechanisms in solid-state NMR imaging are based on relaxation times (T, T2, T p. T ) and chemical shifts. Most studies develop contrast based either on spin density or T2 differences since these show up immediately without the need of modifying the imaging sequence. The unsurpassed soft-matter contrast of NMRI is hard to achieve with competitive methods like X-ray or computer tomography.

The methodological development and applications of solid-state NMR imaging have been progressing steadily, although a substantial gap between liquid and solid imaging remains owing to the intrinsic difficulties involved with solids. There are a number of excellent reviews " in this area covering the literature published prior to 1995.
