Longitudinal Structural MRI in Neurologically Healthy Adults.

ABSTRACT:

Background

Structural brain MRI measures are frequently examined in both healthy and clinical groups, so an understanding of how these measures vary over time is desirable.

Purpose

To test the stability of structural brain MRI measures over time.

Population

In all, 112 healthy volunteers across four sites.

Study type

Retrospective analysis of prospectively acquired data.

Field strength/sequence

3 T, magnetization prepared - rapid gradient echo, and single-shell diffusion sequence.

Assessment

Diffusion, cortical thickness, and volume data from the sensorimotor network were assessed for stability over time across 3 years. Two sites used a Siemens MRI scanner, two sites a Philips scanner.

Statistical tests

The stability of structural measures
