Table 1 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 | – |
