Shape-Based Alignment of Hippocampal Subfields: Evaluation in Postmortem MRI
This paper estimates the accuracy of hippocampal subfield alignment via shape-based normalization. Evaluation takes place in postmortem MRI dataset acquired at 9.4 Tesla with many averages and approximately 0.01 mm3 voxel resolution. Continuous medial representations (cm-reps) are used to establish geometrical correspondences between hippocampal formations in different images; the extent to whi...
متن کاملAutomatic Measurement of Atrophy Rates in Hippocampal Subfields from Longitudinal High-Resolution T2-weighted MRI
Introduction We present the first study to attempt measurements of longitudinal atrophy rates within hippocampal subfields from in vivo T2-weighted MRI. MRI-based focal measurements of longitudinal change within subfields of the hippocampal formation (HF) have great potential clinical value as biomarkers of disease progression in neurological disorders such as Alzheimer’s disease (AD), as patho...
متن کاملAutomated segmentation of hippocampal subfields from ultra-high resolution in vivo MRI.
Recent developments in MRI data acquisition technology are starting to yield images that show anatomical features of the hippocampal formation at an unprecedented level of detail, providing the basis for hippocampal subfield measurement. However, a fundamental bottleneck in MRI studies of the hippocampus at the subfield level is that they currently depend on manual segmentation, a laborious pro...
متن کاملMulti-voxel pattern analysis in human hippocampal subfields
A complete understanding of the hippocampus depends on elucidating the representations and computations that exist in its anatomically distinct subfields. High-resolution structural and functional MRI scanning is starting to permit insights into hippocampal subfields in humans. In parallel, such scanning has facilitated the use of multi-voxel pattern analysis (MVPA) to examine information prese...
متن کاملDifferential effect of age on hippocampal subfields assessed using a new high-resolution 3T MR sequence
Recent advances in neuroimaging have highlighted the interest to differentiate hippocampal subfields for cognitive neurosciences and more notably in assessing the effects of normal and pathological aging. The main goal of the present study is to investigate the effects of normal aging onto the volume of the different hippocampal subfields. For this purpose, we developed a new magnetic resonance...
