Table 4.
Mean values with standard deviation (SD) regarding height, weight and different dose parameters as well as their associated p-values. Since height and weight were recorded during PCCT scans only, these parameters were adopted for the dose calculation of EID-CT scans as well.
| EID | PCCT | Stat. Significance (p) | |
|---|---|---|---|
| Mean SD | Mean SD | EID vs. PCCT | |
| Height in cm | 172.8 ± 10.0 | ||
| Weight in kg | 77.4 ± 16.6 | ||
| DLP in mGy·cm | 112.6 ± 20.6 | 85.9 ± 36.1 | <0.001 |
| CTDIvol in mGy | 3.0 ± 0.6 | 2.5 ± 1.1 | 0.007 |
| Effective dose in mSv | 1.9 ± 0.5 | 1.4 ± 0.6 | <0.001 |
