Comparison of the Abilities of Conventional SE and ARFI Imaging to Differentiate Malignant Thyroid Nodules
| Sensitivity | Specificity | PPV | NPV | Accuracy | |
|---|---|---|---|---|---|
| Conventional SE | 63.2% | 66.3% | 34.4% | 86.6% | 65.6% |
| ARFI imaging | 80.0% | 86.3% | 61.5% | 94.0% | 85.0% |
ARFI = Acoustic Radiation Force Impulse; NPV = negative predict value; PPV = specificity, positive predict value; SE = strain elastography.
