Area of Science:

Neuroimaging
Medical Image Analysis
Computational Neuroscience

Background:

Accurate estimation of cortical thickness is crucial for understanding brain structure and function.
Existing methods for cortical thickness estimation often rely on surface meshes, limiting their applicability to complex anatomical variations.

Purpose of the Study:

To present a new, automatic, and fast voxel-based algorithm for estimating human brain cortical thickness.
To demonstrate the algorithm's applicability to datasets with severe cortical atrophy and high curvature areas.

Main Methods:

A voxel-based approach for cortical thickness estimation, integrated into a brain imaging processing pipeline.
The method focuses on grey matter segmentation and subsequent thickness calculation without using surface meshes.

Main Results:

The developed algorithm provides a practical and efficient method for cortical thickness estimation.
The voxel-based approach overcomes limitations of mesh-based methods, particularly in cases of severe cortical atrophy and thin gyral structures.
Computation times are significantly reduced, typically within minutes.

Conclusions:

This novel voxel-based method offers a practical, automatic, and rapid solution for human brain cortical thickness estimation using MRI.
Its ability to handle severe cortical atrophy makes it a valuable tool for clinical studies and neuroimaging research.
