To evaluate the image quality between two sequences (GRASP vs. CDT-VIBE), as well as two kinds of contrast agents (Gd-EOB-DTPA vs. gadobutrol) in liver DCE-MRI. The qualitative and quantitative evaluations regarding of the image quality, and the detection rates of lesions among four groups were analyzed and compared. The results showed that MR images with GRASP sequence had significantly better image quality and less artifacts than that with CDT-VIBE sequence especially in arterial phase, and MR images with injection of gadobutrol could improve the hepatic vessel clarity and reduce motion artifacts compared with that of Gd-EOB-DTPA in CDT-VIBE sequence.
