To evaluate
clinical performance of contrast-enhanced 3D-isotropic
radial volumetric interpolated breath-hold examination (VIBE) for late-phase MR
imaging of the liver. A prototype retrospective self-gating algorithm for more
motion-robust data acquisition was implemented and compared to standard Cartesian
VIBE. Utilization of self-gating VIBE provides significantly improved image quality,
especially in coronal reformations and Gd-EOB-DTPA-enhanced late-phase scans.
Moreover, in 11% only radial VIBE provided diagnostic image quality, thus having a
direct implication on patient care. Therefore, self-gated radial VIBE seems a
valuable approach to improve diagnostic accuracy in late-phase MR imaging of
the liver.
