This work compares the utility of time-averaged vs. time-resolved dual-venc 4D flow MRI to look at intracranial blood flow distribution for applications such as evaluation of cerebral arteriovenous malformation (AVM). Time-averaged scans provide larger FOV, no additional time for image reconstruction after the scan and net flow distributions that correlate well with time-resolved scans.
