Title

Fractal analysis of magnetic resonance images of the brain

Abstract

The image intensity surfaces of T1-weighted, T2-weighted, and Proton Density-weighted magnetic resonance images of the brain were found to be fractal. A statistical analysis of the fractal dimension showed that normal tissue and abnormal tissue (pathology and edema) could be distinguished by comparing fractal dimensions from the T2-weighted and Proton Density-weighted images. For normal tissue, no significant differences existed among fractal dimensions for T1-weighted, T2-weighted, and Proton Density-weighted images. Based on this study, the fractal dimension comparison between T2-weighted and PD-weighted images could classify normal versus abnormal tissue in MR images.
