- Abstract
- Hydraulic permeability of cancellous bone is an important property for modeling bone and fluid response to mechanical stimuli. It can play a role in design of bone substitutes and cementation procedures. However, this property is poorly understood. Published experimental studies have reported large variations in property values, and there remains no reliable method for predicting the permeability from other observations or measurements. Consideration of spatial variations in properties within laboratory samples raises significant issues regarding the efficacy of permeability determinations from conventional experiments. We use magnetic resonance imaging (MRI) to probe fluid flow and fluid residence at a much finer scale than can be assessed with conventional experiments. We use this information to resolve spatial distributions of porosity and permeability on a bone sample.
