摘要:
Regional pulmonary perfusion is spatially heterogeneous. The classic assumption has been that this is due to the influence of gravity. In the past decade, a new concept has emerged, stressing the fractal geometric properties of the pulmonary vascular tree. Studies that support the gravitational concept tend to have been elaborated using a lower resolution of measurement whereas experiments with high resolution measurements often yield results that contradict the gravitational hypothesis.
