Image-guided biopsies and FNAC

Image-guided biopsies and Fine Needle Aspiration Cytology (FNAC) are medical procedures that use imaging techniques, such as ultrasound, computed tomography (CT), or fluoroscopy, to guide the collection of tissue samples or cells for diagnostic purposes.

During an image-guided biopsy or FNAC, the patient is typically positioned based on the area being targeted for sampling. The skin over the target area is cleaned and sterilized. Local anesthesia may be administered to numb the area, depending on the procedure and patient comfort.

Using real-time imaging guidance, such as ultrasound or CT, a needle or a fine needle is inserted into the target area, which could be a tumor, lesion, or abnormality. The imaging helps guide the needle to the precise location for sample collection.

In the case of a biopsy, a larger needle may be used to extract a tissue sample. The needle is carefully advanced into the target area, and a small piece of tissue is removed for examination under a microscope.

For FNAC, a thin, fine needle is used to extract cellular material from the target area. The needle is inserted into the area of interest, and suction or movement of the needle helps collect cells or clusters of cells for analysis.

Once the sample is collected, the needle is removed, and pressure or a bandage may be applied to the site to control bleeding. The collected tissue or cells are sent to a laboratory for further analysis by pathologists.

Image-guided biopsies and FNAC procedures allow for accurate sampling of tissues or cells from deep-seated or difficult-to-reach areas. They provide valuable diagnostic information, helping in the identification of various conditions, such as tumors, infections, or inflammatory disorders.

In summary, image-guided biopsies and FNAC procedures utilize imaging techniques to guide the collection of tissue samples or cellular material for diagnostic purposes. These procedures enable targeted sampling, aiding in the diagnosis of various medical conditions.
