Derivation of Quality Measures from Time-Series Images by Neuroimaging Pipelines

Using the National Database for Autism Research cloud platform, MRI data were analyzed using neuroimaging pipelines that included packages available as part of the Neuroimaging Informatics Tools and Resources Clearinghouse (NITRC) Computational Environment to derive standardized measures of MR image quality. Time series QA was performed according to Friedman, et al. (http://www.ncbi.nlm.nih.gov/pubmed/16952468) providing values for Signal to Noise Ratio that can be compared to other subjects. Diffusion QA was performed according to Liu, et al. (http://www.ncbi.nlm.nih.gov/pubmed/24353379), which provides a number of pass/fail checks and advisory flags.
