Real-time MRI monitoring of liquid embolic agent (Onyx) injection in a swine arteriovenous malformation model.

<p><br> </p> <p><strong>Movie 1 Real-time, dynamic EPI-GRE T2 scan of the whole brain volume during Onyx injection. Cine sequence of the ONYX propagation at the level of the pons. Dark liquid embolic agent is gradually filling small arteries around the pons.&nbsp;</strong></p> <p>&nbsp;</p> <p><strong>Movie 2 Real-time dynamic EPI-GRE MRI monitoring of the test infusion of diluted gadolinium (10mM) seen as a short wash-in and wash-out of hypointense signal, confirming the proper position of the microcatheter and verifying the area of trans-catheter perfusion.</strong></p>
