Table 1 Likert scale grading of oral contrast distribution in the small bowel (extension and distension)
Extension | Grade | Distention |
|---|---|---|
Segment filled to 100% | 9 | Excellent or almost over distended |
Filling > 75% but < 100% | 8 | Optimal filling |
Filling about 75% | 7 | Good filling |
Filling > 50% but < 75% | 6 | Slightly better than grade 5 |
Filling about 50% | 5 | Medium filled bowel loop |
Filling > 25% but < 50% | 4 | Amount of OCA just allowing for a ROI of 6 mm |
Filling about 25% | 3 | Small amount of OCA, insufficient for placing a ROI of 6 mm |
Traces of OCA filling | 2 | Minimal amount of OCA |
No OCA identified | 1 | No OCA identified |
