Comparison of radiation dose between low-dose and standard-dose imaging
| Low-dose imaging | Standard-dose imaging | p value | |
|---|---|---|---|
| DLP (mGy*cm) | 8.3 (IQR: 7.0) | 226.8 (IQR: 68.5) | < 0.001 |
| CTDIvol (mGy) | 0.3 (IQR: 0.2) | 6.7 (IQR: 1.8) | < 0.001 |
| Effective dose (mSv) | 0.2 (IQR: 0.1) | 4.6 (2.2) | < 0.001 |
| Simulated effective dose1 (mSv) | 0.1 (IQR: 0.0) | 0.9 (IQR: 0.6) | < 0.001 |
