Decay-corrected in vivo distribution of ¹⁸F-Annexin V in UM-SCC-22B tumor bearing mice quantified by PET imaging (n = 9).

Organ	30 min	60 min	120 min
Kidneys	19.2 ± 10.2	7.57 ± 3.08	2.57 ± 0.32
Liver	10.4 ± 3.50	5.23 ± 2.37	2.43 ± 0.49
Blood*	2.98 ± 0.56	1.77 ± 0.46	0.85 ± 0.12
Tumor	1.52 ± 0.31	1.04 ± 0.26	0.59 ± 0.08
Muscle	0.69 ± 0.17	0.52 ± 0.24	0.23 ± 0.06
T/K	0.09 ± 0.03	0.15 ± 0.03	0.23 ± 0.04
T/L	0.15 ± 0.04	0.19 ± 0.01	0.25 ± 0.07
T/B	0.51 ± 0.08	0.59 ± 0.06	0.71 ± 0.14
T/M	2.27 ± 0.53	2.20 ± 0.67	2.76 ± 0.82

The results were presented as mean ± SD (n = 9). Uptake is expressed in %ID/g tissue. Tumor/non-tumor ratios are unitless.

^*Radioactivity in blood was determined by ROI over heart.
