  		Fig. 4 —On chart, different behaviors of correlation of apparent elastic modulus with square of bone volume-to-total volume ratio fraction parameter can be observed depending on analyzed volume of interest (VOI). Small VOI samples present no relationship of dependence with square of bone volume-to-total volume ratio fraction parameter. Large VOI samples have linear behavior and high correlation between apparent elastic modulus and square of bone volume-to-total volume ratio. {square} = large VOI, {triangleup} = small VOI.
