Abstract
Using radial k-space trajectories and under sampling we are able to acquire whole brain high resolution gated PC MRA acquisitions in less than 5 min. This represents an acceleration factor of over 100. In addition, we use a similar strategy to obtain serial images of the entire brain every 0.75s during the passage of a contrast bolus. The serial images are reconstructed using an innovative technique developed in our lab called HYPR. The initial clinical experience using these methods in patients with AVMs will be presented.
Discussion topic:
There are regions of signal drop in the PC velocity fields. Are there Simula software tools that can be adapted to calculate the missing velocities? We are using the PC velocity fields to estimate wall shear stress and pressure.
