A hybrid radial-Cartesian k-space trajectory was used to acquire cine 4D PC MR with ultra-high spatial resolution for anatomical and hemodynamic visualization of small intracranial aneurysms. Specifically, we targeted 12 aneurysms of sizes 2-10mm, with 7 of them 4mm or less. This abstract demonstrates the improved hemodynamic visualization and quantification compared to lower resolution exams typically acquired with Cartesian exams of the same scan length.
