Accurate measurement of human soleus morphological parameters using diffusion tensor and Tl magnetic resonance imaging

摘要

Morphological parameters of a muscle, e.g. fascicle length (FL) and pennation angle (PA), impact the muscle's force generation capacity. These parameters vary between individuals and can be modified due to neurological pathologies. Accurate measurement of human muscle morphological parameters in vivo is still a challenge, nevertheless clinically relevant. The approach presented in the study aims to tackle the inaccuracy of conventional 2D ultrasonographical measurement by using 3D diffusion tensor imaging (DTI). FL and PA of the soleus muscle from three subjects after stroke are presented.
