Quantification of histological tumor volume (DAPI) and total volume in autoradiography (AR total) for ¹⁸F-DCFPyL and ⁶⁸Ga-PSMA and all tumor models. Values are given as mean ± SD (n = 5 in each group). For both tracers and all tumor models, the autoradiographic volume was significantly larger than the histological tumor volume

	Tracer	Model	DAPI	ARtotal	p value
Volume (mm3)	18F-DCFPyL	U87	53.8 ± 38.3	82.8 ± 52.3	< 0.001
		9 L	105.5 ± 18.7	169.8 ± 27.0	< 0.001
		F98	71.4 ± 13.1	132.9 ± 13.3	< 0.001
	68Ga-PSMA	U87	70.1 ± 22.4	95.3 ± 29.4	< 0.001
		9 L	78.6 ± 28.0	107.2 ± 36.0	< 0.001
		F98	58.2 ± 12.0	92.6 ± 8.5	< 0.001
