Synopsis

Keywords: Muscle, MuscleSpontaneous mechanical activities in resting musculature can be visualized using stimulated-echo or spin-echo diffusion-weighted sequences. Temporal resolution is limited to the sampling of one point in time of the contraction pattern. Therefore, a concept for multiple points in time imaging of spontaneous activities is proposed in this work. The implemented MR sequence was validated by measurements from a water phantom and of the resting lower leg musculature of healthy subjects.
