purpose of this study was to elucidate in vivo analysis of the flow dynamics of
ACOM aneurysms from both A1 arteries using 4D-Flow and digital subtraction
out of 8 ACOM aneurysms
showed intra-aneurysm flow from both A1 arteries and 6 other patients showed the unilateral A1 inflow.
Inflow findings of all
patients are consistent with 4D-Flow and DSA. 4D-FLOW MRI is able to visualize
cross flow in ACOM aneurysms.
