Implication

Experimental study demonstrates reliable muscle fiber tracking using diffusion tensor imaging in rat models, indicating its utility for finite element biomechanical simulations.

Key Points

To determine whether diffusion tensor imaging provides accurate and valid skeletal muscle fiber orientation data for numerical biomechanical simulations.
Assessed diffusion tensor imaging (DTI) fiber tracking in rat tibialis anterior muscles by comparing results against fascicle striations in high-resolution MRI and actual physical longitudinal histological sections.
Generated a computational finite element mesh directly from the acquired imaging data to model muscle deformation during active contraction.
DTI-derived fiber directions showed high qualitative agreement with structural striation patterns captured via high-resolution MRI.
An imaging voxel size of 0.9 mm³ established an acceptable quantitative angular accuracy within 5 degrees for biomechanical modeling.
