Investigation and validation of intersite fMRI studies using the same imaging hardware

摘要

PurposeTo provide a between site comparison of functional MRI (fMRI) signal reproducibility in two laboratories equipped with identical imaging hardware and software. Many studies have looked at within subject reliability and more recent efforts have begun to calibrate responses across sites, magnetic field strengths, and software. By comparing identical imaging hardware and software, we provide a benchmark for future multi-site comparisons.
