A novel extension to time resolved angiography using
inflow subtraction (X-TRAILS) is presented. It employs
variable repetition times (vr-TR) to reduce RF exposure
during the multiphase 3D Cones readout to accommodate
patients that exhibit extremely slow intravascular flow
patterns. Bloch simulation including a feasibility study
on subjects is performed. X-TRAILS allows whole head
coverage and the acquisition of both static and dynamic
angiographic high resolution datasets in a single scan.
