Comparison of VCTE and ARFI for evaluation of liver fibrosis in patients with hepatitis C2

Modality	Brand	Stage ≤F2 (no significant fibrosis) a	Stage >F3 (advanced fibrosis/cirrhosis) a	Confounders
VCTE	FibroScan (Echosens)	<7 kPa	>15 kPa	Meal intake, obesity, ascites, steatosis, inflammation, passive congestion, extrahepatic cholestasis
ARFI	Siemens ACUSON S2000	<1.34 m/s	>2.2 m/s	Steatosis, inflammation, passive congestion, extrahepatic cholestasis

ARFI, acoustic radiation force impulse; VCTE, vibration‐controlled transient elastography.

^a Fibrosis as described in METAVIR staging guidelines.
