Dynamic Radial VIBE (DRV) DCE-MRI allows to image with sufficient spatio-temporal resolution for functional imaging of kidneys. However, fast movements of babies during the scan corrupt individual lines in k-space and severely compromise the quality of the reconstructed images and limits the clinical utility of non-sedated imaging. In this work, we evaluate a self-navigated bulk motion detection approach to identify these corrupted lines. We applied this approach on non-sedated infants undergoing feed-and-wrap DCE-MRI with DRV. Our results show that this approach correctly identifies the bulk motion and allows for post-processing correction of the DCE absorption curves.
