DIfferential Subsampling with Cartesian
Ordering (DISCO) is a new high spatiotemporal resolution, dynamic contrast-enhanced
magnetic resonance imaging (MRI) technique. We evaluated the usefulness of multiple
(n=6) hepatic arterial phases (HAPs) with DISCO in gadoxetic acid-enhanced
dynamic MRI for detecting capsular enhancement in hepatocellular carcinoma
(HCC). Such capsular enhancement is detected more frequently by combining portal
venous phase (PVP) images and multiphasic hepatic arterial images with DISCO.
Combining DISCO with PVP improved the liver imaging reporting and data system (LI-RADS)
v2014 score from LR4 to LR5.
