摘要
To obtain hemodynamic descriptors of intracranial aneurismal flow, phase contrast MRI was performed on two aneurysms. To compare accelerated with non-accelerated scans, an acceleration technique called k-t BLAST was applied to one of the scans and compared with the non-accelerated scan. Results showed that velocity magnitude, directions and vorticity could be visualized accurately in non-accelerated measurements, but the accelerated scan showed a significant deviation from the non-accelerated scan.
