Extending work by the QIBA initiative and others, a method is presented here for the generation of configurable digital reference objects (DROs) for the validation of dynamic-contrast enhanced (DCE-) MRI analysis software packages. Five commonly used kinetic models are supported and two software analysis packages were independently tested, one open source and one commercial. A sample set of DROs yielded excellent concordance with ‘ground-truth’ when analyzed with each package, indicating the software’s correctness and providing a benchmark for testing newly written software. Our MATLAB code is provided on an open-source basis to help researchers evaluate and test DCE-MRI analysis software.
