Statistics resulting from the Monte Carlo simulation (10000 samples) for effectiveness and cost of FET PET for diagnosis of recurrent brain metastases

	MRI Alone	MRI + PET	IE	Cost [€]
Mean	0.47	0.89	0.42	1182.43

Minimum	0.33	0.81	0.48	48.33
2.50%	0.38	0.83	0.45	329.62
10%	0.42	0.85	0.43	520.7
Median	0.47	0.9	0.43	1085.59
90%	0.53	0.94	0.41	1965.59

Maximum	0.58	0.96	0.38	4484.82

The 2 center columns represent the 2 alternative diagnostic strategies applying MRI alone or MRI combined with FET PET. The values show the probability of obtaining a correct diagnosis (rounded to 2 decimal places). IE = incremental effectiveness (ie, the benefit that results by adding FET PET to MRI). The right column shows the cost of adding FET PET. SD = standard deviation.
