Abstract:

Objective

To evaluate the value of multimodality ultrasound guided fine needle aspiration (FNA) cytology of thyroid nodules in order to improve the success rate of biopsy.

Methods

From January 2018 to December 2019, 308 patients with 316 nodules who underwent FNA of thyroid nodules were collected from the Department of Medical Ultrasound of the Eighth Affiliated Hospital of Sun Yat-sen University. According to the ultrasonic guidance method of FNA used, the patients were randomly assigned into a conventional ultrasound-guided FNA (US-FNA) group with 81 nodules, contrast-enhanced ultrasound-guided FNA (CEUS-FNA) group with 78 nodules, ultrasound elastography-guided FNA (UE-FNA) group with 78 nodules, and multimodality-FNA group (combined US, CEUS, and UE) with 79 nodules. The FNA cytology results were classified according to the Bethesda system for reporting thyroid cytopathology. The FNA cytology result of each patient was analyzed and the success rates of biopsy in different ultrasonic guidance methods were compared.

Results

The success rates of the multimodality-FNA group, UE-FNA group, CEUS-FNA group, and US-FNA group were 92.4% (73/79), 75.6% (59/78), 71.8% (56/78), and 53.1% (43/81), respectively; the difference among these four groups was statistically significant (χ2=31.797, P<0.001). Pairwise comparison between the groups showed that the success rate of multimodality-FNA group was higher than those in the other three groups (P<0.008).

Conclusion

Multimodality ultrasound-guided FNA of thyroid nodules is helpful to select the malignant thyroid nodules and locate the malignant target areas in thyroid nodules more accurately. Therefore, the success rate of biopsy in FNA is great improved. Multimodality ultrasound-guided FNA is worthy of promotion in clinical work.
