A
new golden angle radial arterial spin labeling acquisition method is proposed
in which labeled blood water is continuously imaged as it passes through the
large arteries and into the tissue. Both
angiographic and perfusion images can then be reconstructed from the same raw
data set at any retrospectively chosen time points and temporal resolution. This makes efficient use of the post-labeling
delay dead time to provide a more complete assessment of blood flow into the
brain, which may be of use in a variety of cerebrovascular diseases.
