free breathing renal magnetic resonance angiography with steady state free precession and slab Selective spin inversion combined with radial k space sampling and water Selective Excitation
Magnetic Resonance in Medicine, 2005Co-Authors: Marcus Katoh, Elmar Spuentrup, Matthias Stuber, Romhild M Hoogeveen, Rolf W Gunther, Arno BueckerAbstract:The impact of radial k-space sampling and water-Selective Excitation on a novel navigator-gated cardiac-triggered slab-Selective inversion prepared 3D steady-state free-precession (SSFP) renal MR angiography (MRA) sequence was investigated. Renal MRA was performed on a 1.5-T MR system using three inversion prepared SSFP approaches: Cartesian (TR/TE: 5.7/2.8 ms, FA: 85 degrees), radial (TR/TE: 5.5/2.7 ms, FA: 85 degrees) SSFP, and radial SSFP combined with water-Selective Excitation (TR/TE: 9.9/4.9 ms, FA: 85 degrees). Radial data acquisition lead to significantly reduced motion artifacts (P < 0.05). SNR and CNR were best using Cartesian SSFP (P < 0.05). Vessel sharpness and vessel length were comparable in all sequences. The addition of a water-Selective Excitation could not improve image quality. In conclusion, radial k-space sampling reduces motion artifacts significantly in slab-Selective inversion prepared renal MRA, while SNR and CNR are decreased. The addition of water-Selective Excitation could not improve the lower CNR in radial scanning.
