The effect of general anesthesia on the test–retest reliability of resting-state fMRI metrics and optimization of scan length

Frontiers in Neuroscience, 2022
Resting-state functional magnetic resonance imaging (rs-fMRI) has been known as a powerful tool in neuroscience. However, exploring the test–retest reliability of the metrics derived from the rs-fMRI BOLD signal is essential, particularly in the studies ...

Intrinsic Frequencies of the Resting-State fMRI Signal: The Frequency Dependence of Functional Connectivity and the Effect of Mode Mixing

Frontiers in Neuroscience, 2019
The frequency characteristics of the resting-state BOLD fMRI (rs-fMRI) signal are of increasing scientific interest, as we discover more frequency-specific biological interpretations. In this work, we use variational mode decomposition (VMD) to precisely

Detecting rs-fMRI Networks in Disorders of Consciousness: Improving Clinical Interpretability. [PDF]

Ann Clin Transl Neurol
Background: Preserved resting-state functional MRI (rs-fMRI) networks are typically observed in Disorders of Consciousness (DOC). Despite the widespread use of rs-fMRI in DOC, a systematic assessment of networks is needed to improve the interpretability ...

A Set of Functional Brain Networks for the Comprehensive Evaluation of Human Characteristics

Frontiers in Neuroscience, 2018
Many human characteristics must be evaluated to comprehensively understand an individual, and measurements of the corresponding cognition/behavior are required. Brain imaging by functional MRI (fMRI) has been widely used to examine brain function related

Integration of resting state functional MRI into clinical practice - A large single institution experience.

PLoS ONE, 2018
Functional magnetic resonance imaging (fMRI) is an important tool for pre-surgical evaluation of eloquent cortex. Classic task-based paradigms require patient participation and individual imaging sequence acquisitions for each functional domain that is ...

Utilizing rs-fMRI’s Mean to Localize Seizure Focus

Open Journal of Radiology, 2015
Purpose: We present for the first time the utilization of an average of the resting-state time points (rs-Mean) to localize epilepsy focus in a group of pediatric patients with medical refractory epilepsy. Materials and Methods: Twenty nine pediatric patients had drug-resistant epilepsy, and 22 subject controls underwent rs-fMRI. Comparison among group

Graphical Structural Learning of rs-fMRI Data in Heavy Smokers

2024 4th International Conference on Computer Science and Blockchain (CCSB)
Recent studies revealed structural and functional brain changes in heavy smokers. However, the specific changes in topological brain connections are not well understood. We used Gaussian Undirected Graphs with the graphical lasso algorithm on rs-fMRI data from smokers and non-smokers to identify significant changes in brain connections.
