Table 1.

Table of contrasts designed into this study. The contrasts are site, vendor, field strength and echo time (TE). “GEL” and GES” stand for the long and short TE values, respectively, acquired from the GE scanner. Sites are labeled by number or field strength if applicable, e.g., “SM1” refers to the first Siemens site and “PH3.0” refers to the Philips 3.0T scanner.
