We compared the breathing motion artifact and signal stability of conventional VIBE, Radial-VIBE with KWIC view-sharing, and CAIPIRINHA-VIBE with moving phantom to simulate breathing motion. Among the three sequences, the CAIPIRINHA-VIBE showed the best image quality, in that the phantom images maintained its shape and just moved its position anteriorly/posteriorly. Thus, the motion correction could align the CAIPIRINHA-VIBE images very well. In terms of signal stability, the CAIPIRINHA-VIBE with motion correction was the best. In conclusion, CAIPIRINHA-VIBE is quite feasible for free-breathing DCE-MRI with high image quality and high temporal resolution.
