The recent development of a multi-modality, commercially available, dynamic flow phantom has provided a means of assessing the repeatability, reproducibility, and fidelity of contrast concentration time courses. In this work, we aimed to develop and evaluate a methodology for assessing the repeatability and reproducibility contrast concentration time courses derived from dynamic contrast-enhanced MR images of this dynamic flow phantom.
