A novel hybrid seed-based approach to assess the test-retest reliability of ICNs is introduced that uses an exhaustive but systematic, ROI-limited search for seed pairs with maximal correlation. We examine the reproducibility of these seed pairs and their relation to four well-known ICNs. We then use this approach to assess test-retest reliability between subjects scanned at 3T and 7T field strengths.
