4D arterial spin labeling (ASL) angiography has gained attention in the diagnosis of cerebrovascular diseases. The aim of this study was to evaluate the feasibility for estimating blood flow rates of the cerebral drainage system using data obtained by a 4D ASL angiography sequence. Data of a 4D ASL angiography acquisition provided comparable flow measurements to those of a standard 2D phase-contrast MR imaging sequence in 12 subjects. We demonstrated that both detailed morphological information and flows rates can be obtained by using a single 4D ASL angiography acquisition.
