Thyroid nodules are common and often require careful evaluation to determine the best course of action. Many patients fear the diagnostic process, but understanding the steps involved can help alleviate these concerns. Dr. Parul Garg offers a comprehensive method for examining thyroid nodules, ensuring accurate diagnosis and effective treatment. Here’s a step-by-step guide to getting your thyroid nodule examined.

Step 1: Ultrasound Examination (TI-RADS Categories)

The first step in evaluating a thyroid nodule is an ultrasound examination. This non-invasive procedure uses sound waves to create detailed images of the thyroid gland and any nodules present. The images are then classified using the Thyroid Imaging Reporting and Data System (TI-RADS) categories, which help assess the risk of malignancy.

  • TI-RADS Categories:
    • TR1 (Benign): No risk of malignancy.
    • TR2 (Not Suspicious): Very low risk of malignancy.
    • TR3 (Mildly Suspicious): Low risk of malignancy.
    • TR4 (Moderately Suspicious): Intermediate risk of malignancy.
    • TR5 (Highly Suspicious): High risk of malignancy.

The TI-RADS system provides a standardized approach to evaluating thyroid nodules, helping to determine which nodules require further investigation.

Step 2: Fine Needle Aspiration Cytology (FNAC)

If the ultrasound indicates that a nodule is suspicious, the next step is Fine Needle Aspiration Cytology (FNAC). This minimally invasive procedure involves using a thin needle to extract a small sample of cells from the thyroid nodule for microscopic examination.

  • FNAC Process:
    • Preparation: The skin over the nodule is cleaned and, if necessary, numbed with a local anesthetic.
    • Aspiration: A fine needle is inserted into the nodule, and a sample of cells is drawn into the needle.
    • Analysis: The sample is sent to a laboratory where a pathologist examines the cells under a microscope to determine if they are benign or malignant.

FNAC is a quick and relatively painless procedure that provides critical information about the nature of the thyroid nodule. Patients often fear FNAC, but it is a safe and essential step in the diagnostic process.
