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.

Weighting (T1, T2)
Thickness (in mm)
Acquisition Plane (Axial, Coronal, Sagittal)
Field Strength (1 - 6)
Coil (8HRBRAIN, BODY, etc.)

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.
