Figure 3.

Examples of hippocampal grading maps obtained on the Bdx‐3C dataset for a sCN subject and a cCN subject 7.5 years before conversion to AD. The blue–purple hippocampal grading map of the sCN subject indicates that a majority of CN‐like anatomical patterns in this subject has been detected. The green areas in the hippocampal grading map of the cCN subject indicate the hippocampal structural patterns of this subject are equally similar to the anatomy of AD and CN ADNI training subjects. Finally, red regions indicate that AD‐like anatomical patterns have been found in this cCN subject 7.5 years before conversion to AD.
