Metric distances between hippocampal shapes indicate different rates of change over time in nondemented and demented subjects.
In this article, we use longitudinal morphometry (shape and size) measures of hippocampus in subjects with mild dementia of Alzheimer type (DAT) and nondemented controls in logistic discrimination. The morphometric measures we use are volume and metric distance measures at baseline and follow-up (two years apart from baseline). Morphometric differences with respect to a template hippocampus wer...
متن کاملAnalysis of Metric Distances and Volumes of Hippocampi Indicates Different Morphometric Changes over Time in Dementia of Alzheimer Type and Nondemented Subjects
In this article, we analyze the morphometry (shape and size) of hippocampus in subjects with very mild dementia of Alzheimer’s type (DAT) and nondemented controls and how the morphometry changes over a two-year period. Morphometric differences with respect to a template hippocampus were measured by the metric distance obtained from the Large Deformation Diffeomorphic Metric Mapping (LDDMM) algo...

Hippocampal sulcus width and cavities: comparison between patients with Alzheimer disease and nondemented elderly subjects.
BACKGROUND AND PURPOSE The hippocampal fissure is a fetal sulcus that, except for its most medial part (the superficial hippocampal sulcus), is normally obliterated. Hippocampal cavities are residual cysts attributable to lack of hippocampal fissure obliteration. We hypothesized that either hippocampal sulcus enlargement or an increase in number or size of hippocampal cavities could be associat...
متن کاملComputable Elastic Distances Between Shapes
We deene distances between geometric curves by the square root of the minimal energy required to transform one curve into the other. The energy is formally deened from a left invariant Riemannian distance on an innnite dimensional group acting on the curves, which can be explicitely computed. The obtained distance boils down to a variational problem for which an optimal matching between the cur...
