Introduction

Thyroid nodules, often asymptomatic, are increasingly detected due to the widespread use of imaging techniques. Appropriate evaluation is crucial to differentiate benign from malignant nodules.

Ultrasound Evaluation

High-resolution thyroid ultrasound is the initial imaging technique of choice, providing information about nodule size, composition, echogenicity, and vascularity.

Fine-Needle Aspiration

Fine-Needle Aspiration (FNA) is the gold standard for cytological evaluation. It classifies nodules into benign, indeterminate, or malignant, guiding further management.

Nuclear Medicine

Scintigraphy helps in functional assessment of nodules. 'Hot' nodules are usually benign, whereas 'cold' nodules warrant further evaluation.

Conclusion

Thyroid nodule evaluation involves a multifaceted approach with ultrasound, FNA, and nuclear medicine playing pivotal roles in diagnosing and managing these nodules.
