Table 1 Single straight pipe phantom: intra-operator variability of semi-quantitative perfusion parameters following five 0.02/0.05/0.08 mL bolus injections of SonoVue^®

	PI	T_PI	Slope of the WI	FWHM	AUC	AUWI	AUWO
0.02 mL/CV (%)	6.03	9.78	9.57	6.43	9.40	9.97	11.11
0.05 mL/CV (%)	9.27	10.14	8.28	13.24	5.23	12.76	6.84
0.08 mL/CV (%)	20.87	10.10	23.52	17.43	5.87	23.72	2.94

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.
