Table 3 Agreement (κ), sensitivity, specificity, and accuracy of target mismatch profile identified by down-sampled CT perfusion and multiphase CT angiography-perfusion versus standard CT perfusion.
From: Multiphase CT angiography perfusion maps for predicting target mismatch and ischemic lesion volumes
κ (95% CI) | Sensitivity (%) | Specificity (%) | Accuracy (%) | |
---|---|---|---|---|
Down-sampled CT perfusion | 0.75 (0.56–0.94) | 42/46 (91) | 13/15 (87) | 55/61 (90) |
Multiphase CT angiography-perfusion | 0.48 (0.22–0.74) | 42/46 (91) | 8/15 (53) | 50/61 (82) |
