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.
