abstract = {The processing and analysis of magnetic resonance images is
highly dependent on the quality of the input data, and
systematic differences in quality can consequently lead to
loss of sensitivity or biased results. However, varying
image properties due to different scanners and acquisition
protocols, as well as subject-specific image interferences,
such as motion artifacts, can be incorporated in the
analysis. A reliable assessment of image quality is
therefore essential to identify critical outliers that may
bias results.Here, we present a quality assessment for
structural (T1-weighted) images using tissue classification
in the SPM/CAT12 ecosystem. We introduce multiple useful
image quality measures, standardize them into quality
scales, and combine them into an integrated structural image
quality rating to facilitate the interpretation and fast
identification of outliers with (motion) artifacts. The
reliability and robustness of the measures are evaluated
using synthetic and real datasets. Our study results
demonstrate that the proposed measures are robust to
simulated segmentation problems and variables of interest,
such as cortical atrophy, age, sex, brain size, and severe
disease-related changes, and might facilitate the separation
of motion artifacts based on within-protocol deviations.The
quality control framework presents a simple but powerful
tool for the use in research and clinical settings.},
