We proposed and assessed a new inversion-prepared
phase-sensitive 3D black-blood (Real-IR BB) imaging
technique combining with white-blood (WB), where the
read-out was GRE and the phase correction for BB was
performed by using 3D Time-of-Flight (TOF) data. The
advantages of our method are the wider slab thickness is
available and no requirements for the data only for
phase correction. Experiments were performed on 3T MRI
for volunteer neck and brain. Optimal TI was regarded as
400-500ms from the views of T1 contrasts among different
tissues and the vessel-to-background contrast. We
concluded that our proposed 3D Real-IR T1W-BB is a
time-efficient vessel-wall imaging method.
