Question Posted 12/11/14:
Hello,
I'm a research assistant at the lab of Dr Jigar Jogia's group, where we will be looking at the changes in MRI data across different conditions, including medications. My problem is that although I have downloaded the medications data, I cannot correlate the patient ID to the MRI data's ID. Is there any way that I can correlate the information on both databases?
Thank you,
Eleftheria

Hi Eleftheria,

You may use the Roster table, in the Enrollment category in Download Study Data.

Compare the PTID (patient_id) and the RID (MRI data's ID).

Due to serious data quality concerns, all data with PTIDs containing the format 381_S_10### have been removed from the ADNI data repository. ADNI leadership strongly advises that data with these PTIDs not be used in any data analysis, submission of abstracts, or publications. Furthermore, ADNI leadership requests that any abstracts or papers which have been submitted using this data be appropriately revised due to concerns with data quality. More information click here.
