Question Posted 10/06/19:
Dear team,
Good Day
I am using MRI and PET images for ADNI for my research. I have trouble finding the MRI/PET images of the same subject under different categories. I have identified the patients who have transitioned from Normal to MCI, Normal to AD, and MCI to AD from the diagnostic summary CSV file. For example, the subject ID, " 023_S_0078" transitioned from MCI to AD. I am looking for MRI and PET images when the patient is in both MCI and AD conditions. I have found the images in MCI, but not in AD. Please help me. Tha
Regards
Emimal

Please refer to the study protocols for schedules of events, which will help to clarify imaging availability for subjects. For example, the ADNI 1 Clinical Protocol states that 'Shortly after the baseline visit,
25% of the subjects in each cohort will undergo a 3T MRI scan while 50% will undergo an
FDG PET scan'. The study protocols can be found in the DOCUMENTS section of the ADNI website.
