Correlation of Blood to Image-derived Blood Surrogates

	n	R²	Slope	rho	SEE/mean
Cerebellum	170	0.84	0.89	0.92	0.06
Cardiac	46	0.84	0.92	0.92	0.07
Aortic	53	0.83	0.87	0.91	0.07
Overall	269	0.84	0.89	0.91	0.06

Correlation results of ID to sampled blood activity. Correlation parameters are R²(coefficient of determination), slope from linear regression, Pearson’s rho and SEE/mean as a measure of coefficient of variation of the regression.
