Ultrasound-guided biopsy, fine needle aspiration cytology (FNAC), or aspiration is a minimally invasive diagnostic procedure that helps in obtaining samples of cells or tissues from an area of interest in the body. Ultrasound, a safe imaging technique, is employed to guide the biopsy needle accurately to the target area. This procedure can be used for various purposes including diagnosing cancers, infections, or other diseases. It can also be used to extract fluid from a cyst or an abscess.
Ultrasound generates images using sound waves. It's non-invasive and doesn't use radiation. The high-frequency sound waves create images of the internal structures, and this real-time imaging allows the doctor to precisely guide the needle to the correct location.
Fasting: Depending on the area being biopsied, you may be instructed to fast for several hours before the procedure.
Medications: Inform your doctor about any medications you are taking, especially blood thinners. You may need to stop taking certain medications before the procedure.
Allergies: Notify your doctor if you have any allergies, especially to local anesthetics.
Clothing: Wear loose and comfortable clothing. You may be asked to change into a hospital gown.
Arrival Time: Arrive at the facility well ahead of time as you may need to complete some paperwork before the procedure.
During the Procedure: You will lie on an examination table. A gel will be applied to the skin over the area to be biopsied, which helps in the movement of the ultrasound probe and enhances image quality. The physician will use the ultrasound to locate the area and then insert a needle to extract cells or fluid.
After the Procedure: The sample will be sent to a laboratory for analysis. You will be given post-procedure care instructions which usually include keeping the biopsy site dry and clean.

It is a procedure where a needle is used to remove cells, tissues, or fluid from the body for analysis. Ultrasound is used to accurately guide the needle to the target area.
It is primarily done for diagnostic purposes, to determine the nature of a lump, mass, or fluid collection. It can help diagnose cancer, infections, or other diseases.
A local anesthetic is usually used to numb the area, so you should not feel pain. You may feel some pressure or discomfort.
Follow your doctor's instructions regarding fasting and medications. Wear comfortable clothing and arrive early to complete necessary paperwork.
The risks are minimal but can include infection, bleeding, or an allergic reaction to the anesthetic.
The procedure itself usually takes only a few minutes, but preparation and post-procedure observation can extend the overall time to about an hour or more.
The timeframe for receiving results can vary, but it usually takes a few days to a week for the samples to be analyzed and the results to be sent to your doctor.
If the results indicate an abnormality, your doctor will discuss the findings with you and recommend further tests or treatment as necessary.
Yes, there are other image-guided biopsy methods such as CT-guided biopsy. The choice depends on the location of the tissue or fluid that needs to be sampled.
Your doctor will provide instructions on how to care for the biopsy site. Generally, it involves keeping the area clean and dry for a certain period.
It depends on the nature of your job and how you feel after the procedure. Some people go back to work the same day, while others may take a day or two off.
Yes, it can be used for various parts of the body including the breast, thyroid, lymph nodes, liver, and others.

Consult your primary care doctor, who will guide you regarding the next steps, which may involve seeing a specialist.
Ultrasound is generally considered safe during pregnancy, but inform your doctor if you are pregnant so that extra precautions can be taken.
