[18F]NaF cardiac and aortic uptake quantification

	Ur	NUr	Ctl
12 weeks old
Cardiac uptake	2.2 ± 0.1	1.9 ± 0.2	1.8 ± 0.1
Aortic uptake	2.8 ± 0.3	1.9 ± 0.3	ND
16 weeks old

[18F]NaF cardiac uptake was assessed in 12 uremic ApoE^−/− (Ur), 9 non-uremic Apo^−/−, and 3 control mice at 12 weeks old and in 9 Ur, 4 NUr, and 4 Ctl at 16 weeks old. [18F]NaF aortic uptake was assessed in 8 Ur and 5 NUr at 12 weeks old and in 4 Ur at 16 weeks old. Results are expressed in arbitrary units. ND not done when there was no visible aortic uptake
