Computer tomograms show vertical gradients in parenchyma
density due to gravity, relating to the mechanical
properties of the lung. Gravitational effects on the
lung were also assessed by a few occasional MRI studies,
but are generally limited by the overall poor SNR of
contemporary methods. Only recently a new ultra-fast
balanced SSFP imaging technique was introduced, offering
exceptional SNR and CNR for in vivo lung imaging at 1.5
T. This makes the investigation of gravity-related
effects in the lung tissue feasible. Here, we develop
the corresponding framework for such MRI investigations,
termed MR Gravimetry of the lung.
