Comparison of Free-Breathing Radial 3D T1 VIBE to Standard Breath-hold 3D T1 VIBE During Hepatobiliary Phase Imaging after Gadoxetic Acid Injection for Image Quality and HCC Detection

The purpose of this study was to compare breath-hold cartesian 3D T1 VIBE (BH-VIBE) to free breathing (FB) Radial-VIBE during hepatobiliary phase (HBP) in terms of image quality (IQ) and HCC detection and lesion conspicuity (LC). Radial-VIBE at HBP phase was comparable in terms of HCC detection to BH-VIBE, with better LC for one reader. Lower degradation of image quality due to respiratory motion artifacts was found for Radial-VIBE in comparison with BH-VIBE for two readers.
