A new fast DB TrueFISP pulse sequence has been developed and applied to high resolution carotid artery imaging. Good flow suppression (> 80%) was achieved with a minor increase in the overall acquisition time (13%). TrueFISP magnetization evolution is maintained in the imaging slice throughout the acquisition, resulting in a low stationary signal disturbance (~10%). Using HEFEWEIZEN, it was possible to visualize moderate and severe carotid artery stenosis on high resolution TrueFISP images with a short acquisition time (<17 s).
