Diagnostic Techniques
Ultrasound and CT Imaging
Ultrasound is a widely used diagnostic technique for evaluating thyroid nodules. It helps in assessing their size, location, and structure, as well as detecting any suspicious features that may indicate malignancy. High-resolution ultrasound is particularly effective in visualizing the borders, shape, and internal components of a nodule, providing crucial information for treatment planning. It is a non-invasive, painless, and cost-effective method, making it the preferred imaging modality for thyroid nodule evaluation1.
Computed tomography (CT) imaging can also play a role in thyroid nodule management, particularly for large nodules, that are difficult to evaluate with ultrasound or when further information is needed2. CT can help in identifying calcifications, infiltration into surrounding tissues, and possible lymph node involvement most thyroid nodules. However, due to the ionizing radiation exposure associated with CT imaging and its limited sensitivity in detecting smaller nodules, it is generally used as a supplementary tool rather than the primary diagnostic technique3.
Fine-Needle Aspiration Biopsy
Once a thyroid nodule is identified through imaging, a fine-needle aspiration biopsy (FNAB) is often performed to determine its nature – benign or malignant4. This minimally invasive procedure involves inserting a thin needle into the nodule’s cells, and extracting a small sample of tissue for microscopic examination. The biopsy samples are then analyzed by a pathologist to identify cellular atypia or other features suggestive of malignancy5.
FNAB is considered the gold standard for diagnosing thyroid nodules due to its high accuracy, minimal risk of complications, and relative affordability6. Moreover, it can be performed under ultrasound guidance, increasing the precision of the procedure and reducing the risk of sampling errors. In cases where the initial FNAB results are inconclusive, the biopsy may be repeated or followed by molecular testing to improve diagnostic accuracy7.
