Assessment of diffusion tensor image quality across sites and vendors using the American College of Radiology head phantom

The purpose of this study was to explore the feasibility of assessing quality of diffusion tensor imaging (DTI) from multiple sites and vendors using American College of Radiology (ACR) phantom. Participating sites (Siemens , GE , and Philips ) reached consensus on parameters for DTI and used the widely available ACR phantom. Tensor data were processed at one site. and eddy current distortions were assessed using grid line displacement on...
