I went to:
https://services.loni.ucla.edu/ida/archive?SubMode=GotoSearch
and did a set of searches, then looked at the fields they used;
Many of the fields are described, but not used (i.e. there are no
instances which have some data in these fields).
Doing this shows that the vast majority of the data lies in MRI/PET,
rather than anything else (MRA, etc.)
HTH,

Ok. From which document did you get the information about the

No, I didn't - chasing down images themselves seems prohibitive at
this time, given constraints.
I would agree with your reading of the terms of use.

publishing any of the content in a demo. Is that your read too?

Dear All,
This is to try an sketch the outlines of the data that seem to be
available in ADNI/ LONI, and so solict requests for additional info.
The Alzheimer's Disease Neuroimaging Initiative (ADNI) maintains an
image database (LONI) of imaging of patients, phantoms and volunteers.
Image types include MRI, fMRI, SPECT, PET, CT and MRA. Some types
appear to have no instances (e.g. fMRI, CT, SPECT).
Each individual is described by an ID number, a type of subject
(Patient/ Volunteer/ Phantom), Sex, Age (as a decimal e.g. 87.4) and
Weight.
However, the age of a patient can change; this is presumably to
allow for different scans at different times
Images are described according to type of imaging; Each subject
(typically) has multiple images. Some choices are given below.
MRI:
Weighting (T1, T2)
Thickness (in mm)
Acquisition Plane (Axial, Coronal, Sagittal)
Field Strength (1 - 6)
Coil (8HRBRAIN, BODY, etc.)
PET:
Frames
Manufacturer (Philips, GE, etc.)
There is then the facility to download images to view (although you
need more permission than I have to do this).
Please let me know if this helps fill in some of the details, and
what else you would like to know.
Matt
