Area under the ROC curves (AUROC) and their 95% confidence intervals (95% CI) for the pancreatic perfusion parameters
| Measured Parameters | AUROC (95% CI) | Cut‐off Value | Sensitivity (95% CI)a | Specificity (95% CI)a |
|---|---|---|---|---|
| TTU (seconds) | 0.50 (0.29–0.71) | ≥18 | 65 (43–82) | 50 (25–75) |
| Tp (seconds) | 0.92 (0.82–1.00) | ≥48 | 90 (70–97) | 83 (55–95) |
| TTW (seconds) | 0.64 (0.44–0.83) | ≥250 | 65 (43–82) | 67 (39–86) |
| PI (MPV) | 0.82 (0.67–0.97) | ≥87 | 80 (58–92) | 75 (47–91) |
| AUC (MPV*s) | 0.81 (0.65–0.96) | ≥13,700 | 70 (48–85) | 83 (55–95) |
TTU, time to initial up‐slope; Tp, peak time; TTW, time to wash‐out; MPV, mean pixel value; PI, peak intensity; AUC, area under the curve.
