Objective To explore the impact factors of time-intensity curve(TIC) in the liver CEUS.Methods Contrast agent in six-doses were injected to 7 healthy volunteers,then common perfusion parameters were acquired from TIC.Results ①Keeping ROI in the same shape and area,the intensity(ΔI) decreased with the depth increased.②In the lower dose(0.5 ml and 1.0 ml),ΔI increased with the dose elevated.③When the shape and area of ROI changed,no statistically different of ΔI was found(P0.05).④ΔI decreased with the deeper focus.⑤ΔI/rise time did not significantly correlated with doses.Conclusion The contrast paremeters are significantly influenced by dose of contrast agent.With the changing of shape and area of ROI,the contrast parameters change scarcely.ROI should be put at proper depth to get satisfactory parameters.The position of the focus has effects on the stability of the microbubbles,therefore influences the results of CEUS.
