Arterial spin labeling (ASL) is a rapidly growing area of interest, primarily because of its ability to provide non-contrast quantitative perfusion maps. 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 3D printed perfusion flow phantom that can be easily replicated, and used to test the precision and repeatability of ASL perfusion measurements.
