Brain Fractal Blood-Oxygen Level Dependent (BOLD) Signals: The Effect of MRI Acquisition Parameters on Temporal Fractal Dimension (FD) Stability

Fractal analysis of the temporal patterns in functional magnetic resonance imaging (fMRI) brain data has recently gained momentum in assessing diseased and pharmacokinetically altered brain. However, there is no agreed standard method of acquisition and analysis. Therefore, we examined the fractal dimension (FD) of the brain's blood oxygen level dependent (BOLD) signal over time, with varying time points, MRI k-space filling techniques, …
