The impact of hippocampal segmentation methods on correlations with clinical data

Abstract

Background: In vivo measurement of hippocampal volume with magnetic resonance imaging (MRI) has become an important element in neuroimaging research. However, hippocampal volumetric findings and their relationship with cardiovascular risk factors and memory performance are still controversial and inconsistent for non-demented adults. Purpose: To compare total and regional hippocampal volumes from manual tracing and automated Freesurfer segmentation methods and their relationship with mid-life clinical data and late-life verbal episodic memory performance in older women. Material and Methods: This study used structural MRI datasets from 161 women who were scanned in 2012 and underwent neurops..
