Table 3 The cut‐off value for hyperaemia Δtd of >0.6 s derived from receiver operating characteristics.
| Parameter | Cut‐off value | Sensitivity | Specificity | AUC | 95% CI |
|---|---|---|---|---|---|
| Δtd rest | >1.0 s | 77 | 67 | 0.77 | 0.66 to 0.88 |
| Δtd hyperaemia | >0.6 s | 90 | 83 | 0.89 | 0.78 to 0.96 |
| MPrest | <1.0 ml/min/g | 65 | 85 | 0.69 | 0.54 to 0.84 |
| MPhyperaemia | <1.6 ml/min/g | 55 | 93 | 0.70 | 0.52 to 0.84 |
AUC, area under the curve; MP, myocardial perfusion; Δtd, slice‐corrected delay time.
