Dynamic Contrast Enhanced (DCE) liver perfusion imaging is a powerful tool for detection and assessment of liver lesions, including hepatocellular carcinoma (HCC). In this work, The IVD-HYCR method is improved by using fluoro-triggering and enabling continuous scanning during the passage of the contrast agent with retrospective identification of multiple breath-hold start times and durations, increasing the methods ability to accurately and consistently acquire high frame-rate images with optimal contrast timing. Continuous scanning during multiple breath-holds and use of data sharing enables acquisition of high spatial and temporal resolution images and numerous time frames, permitting more complete assessment of contrast dynamics.
