The use of balanced steady-state free precession sequences (bSSFP) is an approach to compensate for the signal-to-noise ratio (SNR) loss at lower-field systems (<1T). Low field MRI systems are cheaper, lighter, and less prone to system imperfections than regular 1.5-3T systems, used in clinical practice. In this work, the feasibility and accuracy of velocity encoding using phase-contrast balanced SSFP (PC-bSSFP) is demonstrated and tested on a clinical 3T MRI system ramped down to 0.75T. Phantom and in-vivo results are compared to a standard 2D spoiled gradient echo phase-contrast sequence (PC-GRE).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
