To begin, heat up the xenon polarizer approximately 2.5 hours before the study starts. Thread the connector two of a 250 milliliter specialized polyvinyl fluoride or PVF bag through a ceiling clip. Attach the bag to one of the four available polarizer dispense ports.
On the polarizer touchscreen, select the enriched xenon tank. Set the flow rate to medium and the polarization volume to 250 milliliters. Then press the start button to initiate the polarization process.
Once the polarized xenon gas has been dispensed, the polarizer's touchscreen will display a message to remove the bag. Pinch the connector tube of the specialized PVF bag shut with the ceiling clip, and then disconnect the bag to place it inside the bore of the MRI scanner.
