Clinical Study
Ultrafast Cone-Beam Computed Tomography: A Comparative Study of Imaging Protocols during Image-Guided Therapy Procedure
Table 2
Classification of grading score based on tumor delineation, vascular contrast material perfusion, and appearance of the artifacts.
| Grading point score | Tumor delineation, vascular contrast material perfusion, and appearance of artifacts. | Description |
| 1 | Not suitable for diagnosis (nondiagnostic image data) | 2 | Suboptimal contrast perfusion and tumor delineation, strong appearance of artifacts | 3 | Less than standard contrast perfusion and tumor delineation with hazy appearance of artifacts | 4 | Standard contrast perfusion and tumor delineation with hazy appearance of artifacts | 5 | Vascular contrast material perfusion and tumor delineation are higher than necessary with little or no artifacts |
