We examined temporal rates of change in CC morphology in
MCI patients to determine the differences between
converters to AD and non-converters. The spatial and
temporal patterns of CC morphological change in MCI-NC
are similar to healthy controls, while those in MCI-C
are similar to very mild/mild AD. CC atrophy is
quantifiable in a one-year longitudinal observation
period, making this a practical imaging biomarker.
Amongst the measures considered, circularity proved to
be the most sensitive measure separating convertors from
non-convertors regardless of their gender.
