The purpose of this study is to quantitively and qualitatively evaluate the clinical feasibility of spiral-based TOF-MRA (MRAspiral) in terms of acceleration of data acquisition and imaging performance, with reference to the routine use of TOF-MRA with C-SENSE=4. The results showed that MRAspiral with τ=8 (2min7s) can significantly reduce the acquisition time by 44.3% with a balanced image quality and scan time for arteries visualization and clinical diagnosis.
