MRI Image Data Sets

In the interest of promoting consistency in data analysis, a set of standardized MRI imaging data sets was developed for ADNI1 scans. Researchers are encouraged to utilize these complete data sets in their analysis and to reference them in reporting results. Doing so will help to support direct comparisons of various analysis methods. Details about the rationale and development of the standardized MRI data sets may be found in “Standardization of Analysis Sets for Reporting Results from ADNI MRI data”, Wyman BT et. al.

Standardized MRI Collections

Collections of uniformly pre-processed images corresponding with each of the standardized data sets have been created within the ADNI archive so that researchers may download the complete set of images quickly and efficiently. The collection names and descriptions are shown in the table below.
