The scores for image quality and artifacts

Score	Image quality	Artifacts
0	Unable to perceive the anatomy of the boundary of gray matter and white matter, myelination, and sulcus, rendering the image nondiagnostic	Severe artifact present (underlying anatomy could not be visualized)
1	Inadequate display of anatomy of the boundary of gray matter and white matter, myelination, and sulcus	Moderate artifact present (underlying anatomy could be visualized but delineation was suboptimal)
2	Subpar image quality of the boundary of gray matter and white matter, and myelinization, and the sulcus vaguely displayed, rendering the image inadequate for diagnosis	Mild artifact present (underlying anatomy well-visualized)
3	Visible boundary of gray matter and white matter, and myelinization, with the sulcus vaguely displayed, insufficient soft tissue contrast, but overall acceptability for diagnosis	No artifact
4	Visible boundary of gray matter and white matter, and myelinization, well-defined sulcus, and high soft tissue contrast, rendering the image adequate for diagnosis	–
