Guided FNAC and Biopsies

USG CT GUIDED BIOPSIES

Needle biopsies are often performed with the guidance of computed tomography (CT) and ultrasound. This modality has become a alternative to surgical exploration and biopsy. Needle biopsy is a reliable method of obtaining tissue samples that can help diagnose whether a nodule is benign (non-cancerous) or malignant.

In a biopsy, a small piece of tissue is removed using a biopsy gun or a bart needle which is inserted through the skin into the underlying lesion. The procedure is performed by expert radiologist/pathologist under the presence of a anesthesist and specialized nursing staff. Post procedure proper patient care is given . Recovery time is brief and patients can soon resume their usual activities. This tissue sample is then examined in the lab.

An ultrasound-guided breast biopsy uses sound waves to help locate a lump or abnormality and remove a tissue sample for examination under a microscope. It is less invasive than surgical biopsy, leaves little to no scarring and does not involve exposure to ionizing radiation.

Frequently Asked Questions

This is a procedure performed by a radiologist to obtain a small tissue sample through a needle. This is done to make a diagnosis and plan future management. CT scan is used to guide the needle into the lesion in the safest possible manner.
Most biopsies do not hurt. Some people feel a scratch and stinging sensation when the local anaesthetic is injected, but the skin should then become numb. After this you will be aware of some pushing or sensations of pressure, but not pain. If it is painful more local anaesthetic can be injected.
The technologist will always be able to see and hear you during your exam. You will be asked to hold very still and at times to hold your breath. The imaging physician will perform the biopsy and remove a tissue sample. This biopsy itself usually takes approximately 15 to 30 minutes.
Biopsies may be done under local or general anesthesia. For local anesthesia, medicine is injected to numb your breast. You will be awake, but feel no pain. For general anesthesia, you will be given medicine to put you into a deep sleep during the biopsy.
Do Not:
1. Take blood thinners for at least 3 to 7 days prior to the test. Consult your physician's office for more complete instructions if you are currently taking these medications.
2. Wear earrings or necklaces.
3. Use deodorant, talcum powder or bath oil on the day of the biopsy.
During the procedure:
1. You'll lie on a CT scan table. ...
2. A mark is made on your skin where the needle will be inserted (biopsy site). ...
3. Using the CT pictures as a guide, the needle is passed through the numbed skin between your ribs and into your lung. ...
4. When the procedure is complete, the needle is removed.
Fine Needle Aspiration Cytology (FNAC) is a simple, quick and inexpensive method that is used to sample superficial masses like those found in the neck and is usually performed in the outpatient clinic. It causes minimal trauma to the patient and carries virtually no risk of complications.
When a lump, or a bump is discovered in superficial areas of the body such as the breast and neck, a test known as Fine Needle Aspiration Cytology (FNAC) is recommended to determine whether the lump is cancer. This procedure is also used to test for thyroid, salivary glands and lymph nodes illnesses.
FNAC is generally well-tolerated procedure with most patients experiencing either mild pain or no pain during the procedure. No patients experienced severe pain. There was no difference in VAS scores between lymph node biopsy and salivary gland biopsy.
How Long Does the Procedure Take? Each sample takes about 10 to 20 seconds to obtain. The whole procedure from start to finish usually takes no more than 10 to 15 minutes. However, please allow an hour for your visit because of registration and possible waiting time in the office.
FNAC is performed by an anatomical pathologist assisted by an anatomical pathology technician. It is ideally done with the patient lying down and does not require anaesthetic. In some cases, a topical anaesthetic spray may be used. The test is very straightforward.
The sampling and biopsy considered together are called fine-needle aspiration biopsy (FNAB) or fine-needle aspiration cytology (FNAC) (the latter to emphasize that any aspiration biopsy involves cytopathology, not histopathology). Fine-needle aspiration biopsies are very safe minor surgical procedures.
