Improvements in the 3D PC-MRA calculated from 4D flow MRI are needed for better vessel wall depiction and assessment of vascular dimensions. Balanced steady state free precession (bSSFP) is a promising imaging method to combine with 4D flow for an improved depiction of cardiac anatomy and blood-tissue contrast. This study of 10 healthy subjects compares multiple PC-MRA algorithms using bSSFP with 4D flow magnitude and flow images.
