Conventional Arterial Spin Labeling (ASL) sequence is
limited to the scheme of control/label pairing pulse and
long post-labeling delay, which is an inefficient method
to measure cerebral perfusion. Based on the all in one
scan concept of the Magnetic Resonance Fingerprinting
(MRF), we developed an ASL sequence that does not use
post-labeling delay or control/label pairing to jointly
measure cerebral blood flow (CBF), arterial transit time
and T1. Preliminary scan result in healthy volunteers
and in vascular disease patient showed promises of this
novel technique.
