Going forward we will continue to update this spreadsheet and keep all recalls in one place for clarification. Please continue to read all MRI Core news items though for more information.

The corresponding LONI image IDs are: I36433, I38854, I40669, I40808, I42271, I42810, I47388, I48909, I50986, I50991, I50998, I62689, I65955, I65960, I69528, I70621, I71382, I72154, I72845, I73324

The MR Core found discrepancies in which scale factors were applied because of a duplicate id on the phantom for 1.5T and 3T scans done on the same day. The duplicate ids will be reassigned, the studies will be reprocessed under the new identifiers and re-uploaded to LONI.

In such cases, the MRI Core, through LONI, will make an attempt to contact institutions that have downloaded data identified as incorrect. All investigators should regularly check this site for recall notices and remove data previously downloaded for analysis until corrected data has been posted.
