Fine needle aspiration biopsy (FNAB) is a diagnostic procedure that involves using a special purpose needle to extract cells from a tissue or mass for examination under a microscope. FNAB is a minimally invasive procedure that is widely used in diagnosing cancer, infections, and other conditions. There are several types of special purpose needles used for FNAB, including fine gauge needles, core biopsy needles, and endoscopic ultrasound-guided needles.
Fine gauge needles are the most commonly used Special Purpose Needles for FNAB. They are flexible and thin, allowing for precise and minimally invasive sampling of tissue. Core biopsy needles are larger and can obtain larger tissue samples, while endoscopic ultrasound-guided needles are used for sampling organs in the gastrointestinal tract.
The choice of special purpose needle for FNAB depends on the location and nature of the tissue or mass being sampled, as well as the experience of the medical professional performing the procedure. Overall, FNAB using special purpose needles is a safe and effective way to obtain tissue samples for diagnosis, with minimal risk of complications or side effects.
