Figure 4From: Combined measurement of perfusion, venous oxygen saturation, and skeletal muscle T2* during reactive hyperemia in the legAverage time-course data measured with PIVOT and standard measurement methods. (a) Average perfusion time-course across all young healthy subjects measured with PIVOT (red) and PASL (black). Average SvO2(b) and T2* (c) time-courses measured with PIVOT (blue, green, respectively) and a multi-echo GRE (black). Error bars indicate standard deviation. Grey box indicates period of arterial occlusion.Back to article page
