  1. Lower extremity resting perfusion values from the test and retest scans. The table displays the median and in square brackets, the IQR of perfusion in different muscle groups of the lower legs and feet in ten healthy participants. Statistically significant difference between perfusion in GAS between left and right leg is marked with asterisk (*)
