Scan Time: Approximately 10 minutes
- Run 3 Plane T2 sequences first
- Check notes for each sequence before sending images to Pacs
- If patient cannot hold breath or cooperate with exam, use a negative slice gap equal to one-half the slice thickness (e.g., a 50% slice overlap, so if you are using 4mm slices, use a -2mm gap) and run the sequences without breath holds.
