Title:   The Variability of fMRI Across Site: Results from the Function
Biomedical Informatics Network

Abstract:
The use multiple sites can increase the number of subjects in an fMRI
studies allowing either for the probing of subtle questions or the
group analysis of rare subjects. However, the pooling of data from
multiple sites introduces site-related variability. The Function
Biomedical Informatics Network (fBIRN) Test Bed is a consortium of
sites funded through NCRR to address issues of multi-site acquisition
and integration of fMRI data. This talk will focus on the results from
a recent data acquisition from four sites in the fBIRN. We show that,
when acquisition parameters are matched, the repeatability of the
hemodynamic response amplitude across sites is very reliable. Using
multiple flip angle data, we show that the physiological noise across
site is repeatable, but the thermal noise level is not.

About the speaker:
Douglas Greve received his BS in Electrical Engineering from Tulane
University in 1986, and his PhD in Cognitive and Neural Systems from
Boston University in 1995. He has spent the last 10 years in the
Martinos Center for Biomedical Imaging at Massachusetts General
Hospital studying methods for analyzing fMRI, physiological noise in
fMRI, anatomical analysis with FreeSurfer, multi-modal integration,
and multi-site issues in MRI and fMRI.
