Understanding FNAC and Image-Guided Biopsy: What You Need to Know

What is FNAC (Fine Needle Aspiration Cytology)?

FNAC, or Fine Needle Aspiration Cytology, is a simple test. Doctors use a thin needle to take a small sample of cells from a lump or swelling. Often, this test helps find out if a lump is cancer or something else. Because the needle is very fine, the procedure is quick and usually not painful. Many hospitals and clinics offer FNAC in their diagnostic services.

What is an Image-Guided Biopsy?

An image-guided biopsy uses pictures from scans, like ultrasound or CT, to help doctors guide a needle to the right spot. This way, they can collect tissue from deep inside the body. As a result, image-guided biopsy is helpful when the lump is hard to feel or see. Doctors use this method to get a more accurate sample for testing.

Differences and Similarities Between FNAC and Image-Guided Biopsy

Both FNAC and image-guided biopsy help doctors find out what is causing a lump or abnormal area. However, there are some key differences and similarities:FNAC uses a thin needle to collect cells, while an image-guided biopsy may use a thicker needle to get a tissue sample.FNAC is often done without imaging, but image-guided biopsy always uses scans for guidance.Both tests are usually quick and safe.Doctors use both to check for cancer or infection.

Indications: When and Why Are These Procedures Recommended?
