Summary estimates of the diagnostic criteria and their 95% confidence intervals (CIs) for active IBD lesion on DWI and gadolinium using endoscopic or surgery findings as the gold standard in segment-level analysis
| DWI | Gadolinium | p-valuea | |
|---|---|---|---|
| Sensitivity, % | 62.5 (48.1–75.0) | 45.7 (30.8–61.3) | 0.028 |
| Specificity, % | 97.1 (93.5–98.7) | 98.2 (95.3–99.4) | 0.36 |
| PPV, % | 90.3 (79.4–95.7) | 92.3 (79.3–97.4) | |
| NPV, % | 86.2 (78.9–91.3) | 81.4 (74.0–87.0) | |
| Accuracy, % | 86.9 (80.6–91.3) | 83.1 (76.5–88.1) |
DWI, diffusion-weighted imaging; IBD, inflammatory bowel disease; NPV, negative-predictive value; PPV, positive-predictive value.
