The study supports the validity of brain volumetry using low-field magnetic resonance imaging, as indicated by high intraclass correlation coefficients, high Pearson's correlation coefficients, and low percentage biases across various tissues and brain regions. Some small differences were observed in certain areas.
The volumes of intracranial tissues of 40 healthy volunteers acquired from 0.3- and 3-T scanners were compared using intraclass correlation coefficients, correlation analyses, and Bland-Altman analyses. We found high intraclass correlation coefficients, high Pearson???s correlation coefficients, and low percentage biases in all tissues and most of the brain regions, although small differences were observed in some areas. These findings may support the validity of brain volumetry with low-field magnetic resonance imaging.
