Table 2 Table shows accuracy, sensibility, specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) of Gadoteridol-enhanced MRA and Gadobutrol-enhanced MRA in determining stenosis degree
From: Accuracy of gadoteridol enhanced MR-angiography in the evaluation of carotid artery stenosis
Gadoteridol (n = 42) | Gadobutrol (n = 18) | |

Sensibility | 1 (10/10) | 0.86 (6/7) |
Specificity | 0.91 (29/32) | 1 (11/11) |
PPV | 0.77 (10/13) | 1 (6/6) |
NPV | 1 (29/29) | 0.92 (11/12) |
