We present a DCE-MRI experiment using a commercial perfusion flow phantom for quantitative analysis of image series with high spatial and high temporal resolution (107 ms). Both can be obtained by current real-time MRI methods, i.e. radial undersampled radial FLASH and image reconstruction by nonlinear inversion (NLINV). Contrast agent bolus tracking with high CNR and quantitative parameter maps are presented.
