Ultrasound-Guided Fine-Needle Aspiration

Ultrasound-guided fine-needle aspiration (FNA) is a medical procedure that uses ultrasound imaging to help doctors collect cells from a lump or mass, often in areas like the neck or thyroid. During the procedure, a thin needle is inserted into the area of interest while real-time ultrasound guidance ensures accurate placement. The collected cells are then examined under a microscope to determine if the tissue is benign or malignant. This minimally invasive technique provides valuable diagnostic information with minimal discomfort and low risk, helping doctors make informed treatment decisions efficiently.
