Magnetic resonance imaging (MRI) has become an indispensable diagnostic and research tool. It is capable of visualizing the anatomy and function of organs. Time-resolved three-dimensional (i.e. 4D) MRI blood flow measurements, e.g. arterial spin labeling (ASL) MR angiography (MRA), of the brain is of increasing recent interest due to MRI technology advancements. 4D ASL MRA sequences are now capable of imaging cerebrovascular structures and blood flow with a spatial resolution better than 1 mm
