Ultrasound-guided FNAB

Ultrasound-guided fine-needle aspiration biopsy (FNAB) is a minimally invasive procedure used to collect cells from a suspected lump or abnormal area, such as in the thyroid or lymph nodes. During the procedure, a doctor uses an ultrasound machine to visualize the target tissue in real-time, guiding a thin needle precisely into the area of concern. A small sample of cells is then drawn into the needle and sent to a lab for analysis. This method enhances accuracy, reduces discomfort, and helps diagnose conditions like infections, benign growths, or cancer.
