Table 2 Three intertwined pipe phantom: intra-operator variability of semi-quantitative perfusion parameters following five 0.03/0.06 mL bolus injections of SonoVue^®

	PI	T_PI	Slope of the WI	FWHM	AUC	AUWI	AUWO
0.03 mL/CV (%)	3.16	7.69	9.65	5.56	2.33	8.55	5.32
0.06 mL/CV (%)	7.85	8.60	11.62	7.53	6.73	9.52	6.12

CV: Coefficient of variation; PI: Peak intensity; T_PI: Time to peak intensity; FWHM: Full width at half maximum; AUC: Area under the curve; AUWI: Area under the wash-in; AUWO: Area under the wash-out.
