2024年6月28日 · During this minimally invasive procedure, a provider uses a long, thin needle (22-gauge diameter or smaller) to draw cells and fluid from one or more thyroid nodules. They use ultrasound imaging to guide the needle directly into the nodule. Core-needle biopsy (CNB). This procedure is like FNA, but the needle has a larger diameter (14- to 20-gauge).

An ultrasound-guided fine needle aspiration biopsy uses sound waves to help locate a nodule or abnormality within the thyroid and remove a tissue sample for examination under a microscope. The procedure is less invasive than surgical biopsy, leaves little to no scarring and does not involve exposure to ionizing radiation.

Not everyone who has a thyroid nodule needs a fine needle aspiration biopsy. Your healthcare provider may start with an ultrasound or computed tomography (CT) scan of your neck. Sometimes, this provides enough information to know that the nodule isn’t due to cancer.

If your thyroid has a nodule or other abnormality, a doctor may request an ultrasound-guided fine needle aspiration biopsy. This procedure first uses soundwaves to detect its presence, then a tissue sample is extracted for examination under a microscope.

An ultrasound guided Thyroid / Neck Biopsy is a medical procedure that is performed in order to diagnose the nature of a thyroid nodule. At University Radiology, our interventional radiologists perform biopsies using ultrasound imaging to precisely guide …

Our experienced healthcare professionals can perform a thyroid scan, thyroid ultrasound, or guided FNA biopsy to help with the evaluation of thyroid nodules. We can also discuss treatment options such as radioactive iodine or thyroid RFA to eliminate malignant lesions and noncancerous nodules.

2021年9月1日 · Ultrasound is the first line tool to evaluate thyroid nodules, and can help identify nodules that are high-risk for malignancy. Fine needle aspiration (FNA) is an excellent low-risk procedure used to evaluate suspicious thyroid nodules and identify thyroid malignancy. It is performed with a 22-27-gauge needle under ultrasound guidance.
