Our study assesses the feasibility and quality of non-gated non-contrast-enhanced MRA (NCE MRA) carotid imaging using inversion-prepared bSSFP in 16 volunteers. The sequence offers high-quality images with bright intravascular signal, and results were equivalent or superior to those of standard TOF MRA. Non-gated NCE MRA allows high-quality carotid imaging over a larger field of view with a shorter acquisition time than TOF.
