Synopsis

Keywords: Vascular, Cardiovascular

Motivation: To improve the image quality of the non-enhanced whole heart bTFE CMRA sequence at 3T.

Goal(s): To compare the performance of a newly improved bTFE CMRA sequence with the mDixon water-fat separation GRE method at 3T for CMRA.

Approach: Success rate, acquisition time, image quality, and diagnostic performance were compared.

Results: This study demonstrated that the performance of the 3D bTFE CMRA sequence at 3T was brilliant, with a high success rate, appropriate acquisition time, excellent image quality, and good diagnostic performance.

Impact: The non-enhanced bTFE CMRA sequence at 3T may be recommended for more extensive clinical applications.
