Advanced MRSI acquisition strategies can be complex to implement and require customized reconstruction software, typically designed for a specific raw file format and that relies upon a priori knowledge of the specific implementation of the pulse sequence being applied. The ISMRMRD format1 has begun to address standardization in describing data acquisition parameters for different types of imaging data, but further development is needed. Here we build on this strategy by demonstrating XML encoding of parameters that describe flyback echo-planar, compressed sensing MRSI acquisitions being implemented on scanners from multiple vendors at UCSF that can be supported with generalized reconstruction software.
