OBJECTIVE: To compare free-breathing radially sampled 3D fat suppressed T1-weighted gradient-echo acquisitions (radial volumetric interpolated breath-hold examination [VIBE]) with breath-hold (BH) and free-breathing conventional (rectilinearly sampled k-space) VIBE acquisitions for postcontrast imaging of the liver.
Radial VIBE is a novel 3D gradient-echo sequence that uses a radial stack-of-stars sampling scheme to acquire the k-space information.
