The variability of the parameters measured with diffusion tensor imaging (DTI) is a main concern for the longitudinal studies monitoring disease. We investigated the reproducibility of DTI parameters during one imaging session of one volunteer. The results are highly reproducible showing the stability of scanner performance. The study was repeated on another scanner with different field strength and reproducible diffusion parameters in white matter were seen between scanners.
