Summary

This summary is machine-generated.

Superb microvascular imaging (SMI) significantly improves the detection of metastatic lymph nodes (LNs) in papillary thyroid carcinoma (PTC). Combining SMI with conventional ultrasound (US) enhances diagnostic accuracy for predicting PTC recurrence.

Background:

Metastatic lymph nodes (LNs) in papillary thyroid carcinoma (PTC) are a key factor for disease recurrence.
Accurate diagnosis and prediction of metastatic cervical LNs are crucial for effective patient management.

Purpose of the Study:

To evaluate the diagnostic and predictive value of superb microvascular imaging (SMI) for metastatic cervical LNs in patients with PTC.
To compare the performance of SMI with conventional ultrasound (US).

Main Methods:

Analysis of 183 cervical LNs (103 metastatic, 80 reactive) from 116 PTC patients.
Conventional US and SMI characteristics were assessed, and diagnostic performance was compared using receiver operating characteristic (ROC) analysis.
A nomogram was developed to predict metastatic LNs based on multivariate analysis.

Main Results:

Metastatic LNs showed specific US and SMI features, including L/S < 2, ill-defined borders, and peripheral/mixed vascular patterns.
SMI demonstrated higher sensitivity (94.4%) and specificity (79.3%) compared to US (87.3% and 69.3%, respectively).
The combined use of US and SMI yielded a higher area under the ROC curve (AUC) of 0.926, indicating superior diagnostic accuracy.

Conclusions:

SMI is superior to conventional US for diagnosing metastatic LNs in PTC.
The combination of US and SMI significantly improves diagnostic accuracy for metastatic cervical LNs in PTC.
SMI is an effective tool for differentiating and predicting metastatic cervical LNs in PTC patients.
