Overview

This manuscript presents a protocol for segmenting the human hippocampus and its subfields using MRI. It focuses on providing an anatomically accurate method tailored for high-resolution images.

Key Study Components

Area of Science

• Neuroimaging
• Hippocampal anatomy
• Magnetic resonance imaging

Background

• The hippocampus is crucial for memory and spatial navigation.
• Understanding its subfields can provide insights into neurological conditions.
• High-resolution imaging is essential for accurate segmentation.
• This study aims to enhance neuroimaging techniques for better analysis.

Purpose of Study

• To develop a reliable method for segmenting hippocampal subfields.
• To facilitate research on structural changes in healthy and diseased states.
• To provide definitions for subfields along the entire hippocampal length.

Methods Used

• Utilization of a three T MRI scanner for high-resolution imaging.
• Segmentation of the hippocampus into five subfields: CA1, CA2/CA3, CA4/dentate gyrus, strata radiatum/lacunosum/moleculare, and subiculum.
• Software interface for segmentation analysis.
• Command-line instructions for initiating the segmentation process.

Main Results

• The protocol allows for accurate segmentation of hippocampal subfields.
• It provides a framework for analyzing structural changes in various conditions.
• Results can enhance understanding of hippocampal function and pathology.
• High-resolution images improve the reliability of the findings.

Conclusions

• The developed protocol is a significant advancement in neuroimaging techniques.
• It can aid in research related to memory disorders and other neurological conditions.
• Future studies can build upon this method for further insights into hippocampal function.
