Un protocolo integral para la segmentación manual de las estructuras mediales Temporal Lobe

Overview

This work outlines a detailed protocol for manually tracing the medial temporal lobe (MTL) structures using high-resolution magnetic resonance images. The method is applicable to both healthy and clinical populations in structural and functional MRI studies.

Key Study Components

Area of Science

• Neuroscience
• Neuroimaging
• Structural Biology

Background

• The medial temporal lobe is crucial for memory and spatial navigation.
• Manual tracing allows for precise delineation of brain structures.
• High-resolution MRI provides detailed anatomical information.
• This protocol aids in understanding MTL variations in different populations.

Purpose of Study

• To provide guidelines for tracing MTL structures.
• To facilitate research on MTL in various clinical contexts.
• To enhance the accuracy of volumetric assessments of brain structures.

Methods Used

• Identification of the amygdala and systematic tracing from anterior to posterior.
• Locating and tracing the hippocampus slice by slice.
• Tracing the anterior structures of the para hippocampal gyrus.
• Tracing the posterior segment of the para hippocampal gyrus.

Main Results

• Successful manual tracing of MTL structures was achieved.
• 3D renderings and volumetric statistics were obtained.
• The protocol demonstrated applicability across different populations.
• Variations in mutual borders of structures were accommodated.

Conclusions

• This protocol provides a reliable method for MTL tracing.
• It can be utilized in both healthy and clinical research settings.
• The approach enhances the understanding of MTL anatomy and its variations.
