Table 1. The mean and standard deviations of the absolute discrepancy measurements of volume, VOI selection and segmentation between observers (inter) and within-observer (intra) in MSCT and in CBCT data.
| Scanner type | Observer relation | Volume/mm3 | VOI/mm | Segmentation/mm |
|---|---|---|---|---|
| MSCT | Intra | 120.0±92.6 | 0.9±0.8 | 0.1±0.2 |
| Inter | 178.6±149.3 | 0.8±0.8 | 0.3±0.3 | |
| CBCT | Intra | 136.1±143.5 | 0.5±0.5 | 0.2±0.2 |
| Inter | 174.1±201.1 | 0.7±0.7 | 0.2±0.2 |
CBCT, cone-beam computed tomography; MSCT, multi-slice computed tomography; VOI, volume of interest.
