Implication

Imaging validation study demonstrates rapid visualization of complex forearm muscle architecture, indicating high accuracy confirmed by cadaver dissection.

Key Points

To design a time-efficient, clinically feasible diffusion-tensor MRI protocol and postprocessing pipeline to characterize the complex muscle architecture of the human forearm.
Acquired in vivo images on a 3 T scanner in a 15-minute protocol comprising T1-weighted, dual-echo gradient echo, and single-shot spin-echo echo-planar diffusion-tensor imaging.
Applied postprocessing algorithms including Rician noise suppression, motion and eddy-current registration, magnetic field inhomogeneity correction, and fiber tractography seeded from 1 to 5 regions of interest per muscle.
Validated in vivo 3D muscle reconstructions against anatomical photographs of dissected human cadaver forearms.
Integrated postprocessing was essential to achieve accurate muscle segmentation and fiber reconstruction from combined T1-weighted and diffusion-tensor data.
The protocol generated detailed in vivo visualizations of forearm muscle architecture that showed high qualitative agreement with dissected cadaver specimens.
