The imaging procedure is based on a well defined phantom (a modified ADNI design) and will be performed using two different 1.5T MR scanners per imaging company (one newer scanner, one in widespread use). Imaging will be performed at select US clinical sites. Image and resulting data analysis will be performed centrally to provide a consistent analysis quality for further decision making. The phantom study is planned for three months.
