Synopsis

Keywords: Muscle, Pulse Sequence Design

Motivation: Investigating contractile behavior of spontaneous muscular activities in healthy subjects using DW-MRI to better understand these contractions.

Goal(s): To investigate the influence of sequence settings on recording spontaneous muscular activities.

Approach: Applying a single-shot multiple point in time sequence with varying parameterization for determining differences in the visual representation of these activities.

Results: Significant differences in the visual representation of spontaneous muscular activities were found.

Impact: Imaging properties for assessing contractile behavior of spontaneous muscular activities using DW-MRI were determined. A large influence on the imaging results was revealed which might be important for further studies in healthy subjects and patients suffering from neuromuscular disease.
