Summary
Shear wave elastography (SWE) improves ultrasound accuracy in diagnosing thyroid nodules. This tool enhances the American Thyroid Association (ATA) guidelines for better malignancy prediction in low-suspicion cases.
Area of Science:
- Endocrinology
- Medical Imaging
- Oncology
Background:
- Diagnosing thyroid nodules with intermediate- and low-suspicion patterns is challenging using the 2015 American Thyroid Association (ATA) stratification.
- Ultrasound (US) is a primary imaging modality, but its accuracy can be limited for certain nodule types.
Purpose of the Study:
- To evaluate shear wave elastography (SWE) as an adjunctive tool to ultrasound (US) for improving the prediction of malignancy in thyroid nodules.
- To assess the performance of SWE in differentiating benign from malignant nodules, particularly those with indeterminate risk.
Main Methods:
- A study involving 270 thyroid nodules with low or intermediate suspicion for malignancy was conducted between January and April 2018.
- Maximum SWE elasticity values (Emax) were measured and correlated with pathological findings.
- Diagnostic performance was compared between ATA guidelines alone, SWE alone, and a combined approach.
Main Results:
- The combination of SWE and ATA guidelines demonstrated superior diagnostic accuracy (AUC 0.81) compared to ATA guidelines alone (AUC 0.72).
- Malignancy rates for low and intermediate suspicion nodules were 21.1% and 54.2% respectively by ATA. After SWE integration, restratified suspicion levels showed malignancy rates of 0% (very low), 27.3% (low), 37.8% (intermediate), and 76.9% (high).
Conclusions:
- Shear wave elastography (SWE) can effectively supplement the American Thyroid Association (ATA) pattern in differentiating malignant from benign thyroid nodules.
- The combined use of SWE with US and ATA guidelines enhances the prediction of malignancy for thyroid nodules with low and intermediate suspicion.
