Table 2 Grading scale for subjective image quality analysis of CT examinations.
Qualitative grading scale | Image noise | Vessel sharpness | Beam-hardening artifact | Reconstruction artifact | Overall image quality |
---|---|---|---|---|---|
1 | Unacceptable noise | Blurry border | Many streak artifacts | Many reconstruction artifacts | Unacceptable |
2 | Above-average noise | Ill-defined border | Moderate streak artifacts | Moderate reconstruction artifacts | Suboptimal |
3 | Average noise | Defined Border | Minimum streak artifacts | Minimum reconstruction artifacts | Acceptable |
4 | Less-than-average noise | Clearly defined border | No perceptible streak artifacts | No perceptible reconstruction artifacts | Good |
5 | Minimum or no noise | Sharply defined border | No perceptible streak artifacts | No perceptible reconstruction artifacts | Superior |
The scores of 3–5 for overall image quality were acceptable for diagnosis of liver disease. |
