Article Synopsis
- Resting-state fMRI (rsfMRI) often suffers from low test-retest reliability, prompting researchers to suggest longer scan times and larger sample sizes, which can be challenging in rare populations.
- The study investigated whether dynamic causal modeling (DCM) could improve the reliability of effective connectivity (EC) metrics in rsfMRI without requiring excessively long scans or large sample sizes.
- Results showed that 10.8-minute scans achieved a high accuracy rate (92%) without needing longer durations, and increasing sample sizes improved reliability, plateauing at around 70 subjects for optimal EC analysis.
