Hemodynamic and morphologic changes of peripheral hepatic vasculature in cirrhotic liver disease: A preliminary study using contrast-enhanced coded phase inversion harmonic ultrasonography

Table 1 Microbubble arrival time at hepatic vessels (mean±SD)

	Artery (n)	Portal vein (n)	Hepatic vein (n)
Cirrhosis	16.4±5.3 (5)	21.3±6.7 (3)	21.3±7.7 (3)
Chronic hepatitis	23.5±9.1 (8)	35.1±19.4 (8)	44.3±20.8 (7)
Normal control	20.3±5.4 (4)	31.3±6.7 (3)	45.5±17.1 (4)
P1	0.537	0.077	0.046
P2	0.185	0.26	0.03

P 1: Comparison between cirrhosis and normal control. P 2: Comparison between cirrhosis and chronic hepatitis.
