Recent developed methods for non-invasively studying
muscle architecture in humans in vivo include
Ultrasonography (US) and Diffusion Tensor Imaging (DTI).
Many studies have used either US or DTI, but there has
been little or no research comparing the two techniques.
The goal of this study was to compare the results of US
and DTI for measuring human muscle fiber orientation in
vivo. The data presented in this abstract indicate good
agreement between manual US and DTI, supporting the use
of DTI for in vivo muscle architecture measurements.
