Keywords: New Trajectories & Spatial Encoding Methods, Blood vesselsA spiral multiband localized quadratic encoding (LQE) method is proposed to achieve simultaneous brain and neck time of flight MRA within a single 2.5-minute scan. LQE acquisition is efficient for both SNR and in-flow enhancement. Multi-band LQE enables increased coverage with no increase in scan time, but can introduce venous signal contamination. We propose a multi-band LQE approach with TONE and partial-Fourier slice selection to reduce the venous signal and achieve simultaneous time-of-flight MRA of intracranial and carotid arteries.
