Fine-needle aspiration (FNA) uses a needle and syringe to get a tissue or fluid sample from a suspicious mass in your body. Healthcare providers use it to help diagnose abnormal tissue in several areas of your body, such as your breasts, thyroid and lymph nodes.
Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained, are examined under a microscope (biopsy).
Fine needle aspiration is a type of biopsy procedure. In fine needle aspiration, a thin needle is inserted into an area of abnormal-appearing tissue or body fluid.
Fine-needle aspiration is a minimally invasive way to get a cell sample from a lesion with the smallest chance of damaging surrounding healthy tissue. In situations of clinical uncertainty, it is a powerful tool to assist in guiding treatment.
In an FNA, the doctor uses a very thin, hollow needle attached to a syringe to withdraw (aspirate) a small amount of breast tissue or fluid from a suspicious area. FNA is most often done if the suspicious area is likely to be a fluid-filled sac (a cyst).
Fine-needle aspiration and core needle biopsy are minimally invasive sampling modalities that have unique benefits and limitations. Appreciating these differences can help the cytopathologist choose ...
Cytologic evaluation of specimens obtained by fine needle aspiration from lesions of all body sites. Special Instructions. Include patient's name, date of birth, Social Security number, source, previous malignancy, drug therapy, radiation therapy, and all other pertinent clinical information on the test request form.
Fine needle aspiration cytology (FNAC) entails using a narrow gauge (25-22G) needle to collect a sample of a lesion for microscopic examination. It allows a minimally invasive, rapid diagnosis of tissue but does not preserve its histological architecture.
The superficial fine-needle aspiration (FNA) procedure involves using a fine-gauge needle to extract cells from a palpable mass or nodule. The most common anatomic sites for superficial FNAs include thyroid, breast, lymph node, salivary glands, and subcutaneous soft tissue.
Fine-needle aspiration (FNA) cytology is widely used in clinical practice as a simple and minimally invasive test for parotid tumors that allows for preoperative estimation of benignancy and malignancy, histological type, and malignancy grade and can be performed on an outpatient basis.
