Tissue-to-plasma ratios for different organs across time points for all subjects. The light gray dashed horizontal line denotes the estimated tissue-plasma ratio if the label was confined to the vasculature only. The dark gray horizontal dashed line denotes an estimation for when the label concentration in organ interstitial space is equal to that in plasma. Subject 105-light blue, 110-orange, 122-gray, 123-yellow, 125-purple, 127-green, 132-dark blue, 135-brown
