For this purpose, different sequence settings and measurement parameters are applied.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A single\u2010shot MP\u2010DW\u2010STE imaging sequence with multiple signal rephasing by small flip angle RF pulses was developed to acquire image series during spontaneous muscle contractions with duration of several hundred milliseconds. Measurements were conducted on an incoherent motion phantom and in the calf muscles of eight healthy volunteers. The number and cross\u2010sectional area of SMAM visualizations as well as the contractile behavior in terms of onset and duration of visible SMAMs was analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Measurements on the incoherent motion phantom confirmed the ability of the proposed technique to characterize dynamic incoherent motion as signal voids in series of images with a high temporal resolution of approximately 40\u2009ms. All human subjects showed SMAMs with a median duration of 120\u2009ms, therefore, visible in several diffusion\u2010weighted images in a row. Contraction time of SMAMs was in the range of 80 to 120\u2009ms for the soleus muscle. The MP\u2010DW\u2010STE sequence settings have shown to significantly influence the mean frequency and cross\u2010sectional area of SMAMs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>MP\u2010DW\u2010STE imaging allows for time\u2010resolved recording of spontaneous muscular contractions and provides new insights into their dynamic course.
