Arterial spin labeling (ASL) is a rapidly growing area of interest, primarily because of its ability to provide quantitative perfusion maps non-invasively. But, for the technique to be adopted for clinical use, these quantitative measurements need to be accurate and robust, which will require a quality controlled perfusion phantom to ensure consistency for different magnet strengths and manufacturers. In this study, we demonstrate a simple perfusion flow phantom that can be used to test the precision and repeatability of ASL perfusion measurements.
