A bug has been identified in a fraction of de-faced Magnitude DICOM series for multi-echo GRE (ME-T2starw) MRI sequences, wherein volumes were assembled in the incorrect order with incorrect echo times. We have included a list of affected images. For ADNI, this was 140 image series, roughly 16% of MEGRE magnitude series available. Users who have downloaded affected image IDs, or QSM analyses containing them, should delete their copies and any downstream analyses. We are in the process of removing all affected images from LONI and uploading corrected DICOM to replace them, in the next 1-2 weeks. These replacements will have new LONI ImageIDs. We apologize for not catching this error, and we thank the Michael Ewers lab at LMU Munich for bring it to our attention. Thank you for your understanding!

To obtain a listing of removed image series, please download from the IDA, the dataset labeled “Data Advisory: Listing of removed multi-echo GRE (ME-T2starw) images.
