Classification of Agreement Between Reviewers and Automated Measures
| Bowel Dilation Maximum | ≤5 mm | ≤3 mm | ≤1 mm |
| Radiologist-Radiologist | 76.9% | 57.2% | 20.7% |
| Radiologist-SemiAutoMeasures | 72.7% | 52.2% | 22.3% |
| Bowel Wall Thickness Maximum | ≤3 mm | ≤2 mm | ≤1 mm |
| Radiologist to Radiologist | 88.9% | 72.8% | 44.8% |
| SemiAutoMeasures to Radiologist | 89.6% | 79.2% | 38.4% |
| Lumen Diameter Minimum | ≤3 mm | ≤2 mm | ≤1 mm |
| Radiologist-Radiologist | 69.5% | 41.2% | 22.8% |
| Radiologist-SemiAutoMeasures | 76.3% | 52.3% | 22.3% |
Measurement differences were classified into clinically relevant groups to highlight degree of agreement between reference radiologists and semi-automated measures to mean radiologist measurements. Percentages shown represent the portion of all cases where paired measurements were within the indicated difference class.
