Qualitative scoring method used for classifying image artifact.
| I | Visualized | No distinguishable artifact in either sagittal or axial images of the spinal canal or bilateral neural foramina. |
| II | Partially Distorted | Distortion of either neural foramina or the spinal canal that allows partial visualization of the neural structures. |
| III | Fully Distorted | Inability to visualize the neural structures in bilateral neural foramina and the canal. |
