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.
