This study focused on the feasibility of volumetric-interpolated breath-hold examination (VIBE) using compressed sensing (CS) acceleration (CS-VIBE) for the hepatobiliary phase of Gd-EOB-DTPA-enhanced MRI in comparison with conventional VIBE. Our results showed a significantly higher signal-to-noise ratio and contrast-to-noise ratio (CNR) in CS-VIBE than in conventional VIBE. CS-VIBE showed a significantly higher CNR than conventional VIBE, even when decreasing a slice thickness from 1.5 mm to 1.1 mm of CS-VIBE. These results suggested CS-VIBE could replace conventional VIBE with superior CNR and spatial resolution.
