- When setting up a gradient echo field map on a Siemens scanner, make sure you select to store both magnitude and phase images.
- For users of Siemens VA…VE systems (like your VD13C), I would also strongly recommend saving field map data as mosaics: Siemens reuses instance numbers (0020,0013) across echoes, any many PACS systems assume these are identical images so they overwrite images. Depending on your PACS and storage system, it is also possible that phase maps overwrote your magnitude images: to check this export the images directly off your console to a USB drive. I want to be clear that users of Siemens XA systems should NEVER save images in mosaic format.
- Scientists working with Siemens scanners have access to Siemens Research Collaboration Managers. They have encyclopedic knowledge of these systems and are an invaluable resource for resolving issues and tuning performance.
