A 3D Interleaved Variable Density sampling pattern was used with HYCR to generate hepatic and renal dynamic contrast enhanced images of healthy volunteers. A flexible breath-holding scheme was used to maximize patient comfort. Data was retrospectively binned into periods of no breathing motion and HYCR composite image was limited to these periods. Results show high quality DCE images with healthy uptake curves in liver parenchyma, renal cortex and renal medulla.
