Question Posted 05/06/14:
Hi, I am working on MR images. I have identified patients converted from MCI to AD. I have also collected the available data of those patients. But how to know which data are of MCI stage and which are after conversion?

Please reference the data dictionary.
Examination Date in the PDXCONV.csv and DXSUM.csv will list the dates of any diagnostic change.
